  • About

    Hi, I am Andrea Kartika Deierlein. I am a Reiki practitioner & teacher.


    Reiki is a system of natural healing from Japan that is based on mindfulness practices and light touch.

    Reiki sessions help promote relaxation, stimulate the body's innate healing response, and support personal development. For greater benefit, recipients are encouraged to become active participants in their own healing journey. Rooted in the belief that to heal means to make whole, Reiki addresses body, mind and spirit.

    How Reiki has been helping my clients

    "Thank you so much for your caring and your authenticity! I started Reiki understanding that it's a journey. Not a quick fix. Although individual sessions do have measurable results: I ALWAYS feel better the day after a session."

    - Stan N. | Reiki Thriver in Hartsdale, N.Y.


    "My second session with Andrea was transformational. The energy and power quieted my mind and soothed my soul. I am so grateful to have her healing energy in my life."

    - Laura C. | Reiki Thriver in Port Chester, N.Y.


    Insomnia, anxiety & a mind that wouldn't calm down

    Male client, 58, financial executive

    Reiki sessions helped to calm him down and he was able to fall and stay asleep during sessions. He was finally able to relax and find relief, something he wasn't able to experience despite years of exercise and therapy. Before his personal trainer recommended Reiki to him, he was even considering shock therapy to "shut off his mind."


    Depression and anxiety

    Male client, 60, attorney

    Reiki sessions have helped him to connect with himself and what brings him joy again. He has also learned some tools how to deal with daily life's stresses in a productive way. He now practices Reiki self-care every morning and continues to come for regular Reiki sessions for support.


    Chronic neck pain

    Male client, 50, banker

    Regular Reiki sessions help him feel nurtured and taken care of. Instead of pushing himself all the time, he now experiences more compassion and time for himself, with his son and meditation.


    Support during and after cancer treatment

    Female client, 49, teacher

    Reiki sessions have helped her balance the harshness of chemotherapy treatments. During a session she felt like the fear has been lifted off her. In addition to weekly Reiki sessions, she has learned Reiki for herself. She now uses meditation and daily Reiki self-care to keep herself balanced and supported during her healing journey.



    Female client, 40, real estate sales

    Reiki sessions helped with her anxious feelings regarding her life and feelings of unworthiness. She has learned to relax and calm down. Learning Reiki self-care for herself, she was amazed that she has the power to help and heal herself.


    Curious how Reiki can help you, too? 

  • Meet your practitioner.

    Hello. I am Andrea Kartika Deierlein.

    Andrea Deierlein - Reiki practitioner

    For many years, I was one of those walking zombies on Metro North going into the City at 8 a.m., returning 12 or more hours later. I was exhausted, drained, and nasty. To get through the days of my job in German government relations I fueled myself with caffeine and sugar. To deal with the physical pain of all this tension and stress, I popped pain killers like candy. No wonder that I couldn’t sleep and developed a chronically inflamed esophagus, grinding my teeth until some of them broke. During that time one of my colleagues offered to share Reiki with me at our lunch break. To be honest, I didn't think much of it and didn't feel anything.


    Then I moved to Jakarta, Indonesia, where I have always wanted to live. But despite the change of scenery and lifestyle, I was still so much in my head that I continued to repeat my same patterns of perfectionism and pushing myself too hard in my job as Director of Marketing & Communications. Thanks to a friend, I began to join a meditation group and was re-introduced to Reiki. I signed up for a session and experienced the relaxation and relief I desperately needed. It took several sessions, but once my body could recover from all the tension and pain, my mind became clearer, and I realized that all this time I had been working against myself, instead of with myself.
    When I took my first Reiki class in 2015, a switch turned in my head. For the first time in my life, somebody gave me permission to be kind to myself. I am now realizing every day that (self) compassion is more important than functioning and impressing with achievements. Reiki has been my lifesaver, what keeps me sane and well every day. My doctor even declared me “super healthy” after my recent physical. Reiki is a way of well-being that I am committed to share with others.

    My Reiki Training

    My official title is Reiki Master. But since I believe that it takes a lifetime to achieve mastery, I prefer to call myself a Reiki practitioner & teacher. I was trained in the two main traditions of Reiki practice, Usui Shiki Ryoho and Usui Reiki Ryoho, and practice Reiki without any add-ons, bells and whistles. Committed to present, practice and teach Reiki in a practical, authentic and pure way, I am a graduate teacher of the International House of Reiki and continue to work with several mentors and teachers. Check out my profile on the International House of Reiki website here.

    • First degree training with Joshua Lie (July 2015).
    • Second and third degree training with Joanna Crespo, New York Open Center School of Holistic and Professional Learning (October 2015 through April 2016).
    • Shinpiden level with the “teacher of the teachers” Frans Stiene, International House of Reiki (September 2017).

    How many sessions?

    Please do not expect to be "healed" in one session.

    What brings you here has most likely developed over a period of time, sometimes months or even years. Reiki works best accumulatively over time. Try several sessions, at least three, before you decide if Reiki is right for you.

    How does Reiki work?

    Reiki is not magic and not woo woo, yet it works in miraculous ways.

    Sessions stimulate the body's relaxation and self-healing responses and restore balance, physically, emotionally, and mentally.

    As a complementary alternative healing modality, Reiki does not replace conventional medical or psychological treatment. Please see this fact sheet from the National Center for Complementary and Alternative Medicine.

  • Testimonials


    Reiki is best experienced in order to be explained. Here's what some of my clients say. You can find and read more reviews on Google and Facebook.

    "I recommend it to everybody!! Beautiful experience! Beautiful person with pure good intentions. Open your heart and try it! You won't regret it. Blessings!"

    - Romina G., Greenwich, CT

    "We need more people like you in this community! Your philosophy and practice of Reiki, mindfulness and meditation is right on, leveraging the evidence-based niche of modern healing! You are a Reiki Star and an inspiration to many!"

    - Cristina O., White Plains, N.Y.

    "I have had a lot of experiences with Reiki over the last 20 years. Andrea is hands down the clearest and strongest channel for this beautiful healing that I have ever experienced. I have had several private sessions with her and even re-did my Reiki 1 training with her so that I could learn from the best."

    - Alyse S., Stamford, CT

    "I felt at peace and at ease after my first session with Andrea. If you live with chronic pain or anxiety, I would highly recommend adding Reiki to your self-care routine. And I would start with Andrea at Thrive Reiki. She is one of the kindest and most caring people that I've known."

    - Joe F., Valhalla, N.Y.

    "Andrea is a truly gifted, kind, caring and authentic Reiki practitioner. From the moment I met her, I instantly felt comfortable and at ease (which is difficult for me). I have heard about Reiki as a healing modality to help with anxiety and some health issues that I was struggling with and was interested in trying it out after using other traditional healing modalities with little progress in the big picture. Once I started to see Andrea, I felt a real shift in how I was feeling. The best way to explain it is that I feel like the best version of myself. Happier, more energetic, less worried, healthier and, suddenly, life is easier to deal with. The best thing I did was get the courage to give this a shot. In my case, I have been going to weekly sessions and have been making tremendous progress."

    - Alisa A., Bronxville, N.Y.

    "Wow! The energy emanating from Andrea's hands as she lightly touched my head was something that I had never felt before. I even signed up to take classes and become a practitioner. I have completed the first level and look forward to continuing with Andrea for the second level. Andrea is always positive, sincere, kind, and very easy to talk with. She provides ongoing support and opportunities to deepen our practice and also provides many helpful resources. Reiki requires no lifestyle change, but it will definitely change your life for the better. It is a worthwhile practice to look into and learn more about. And Andrea is the Master to teach you!"

    - Barbara P., Yonkers, N.Y.

    "I want to thank you for the wonderful Reiki session. I feel so much stronger from the inside out and have much more clarity. Bless you. You are a true disciple of Mikao Usui. Reiki is safe in your hands and your ability to educate and reach so many people with it is awe inspiring."

    - Breda C., White Plains, N.Y.

    "From the moment I met Andrea I felt a sense of compassion and attentiveness coming from her. Doing my first session I felt the stress lifting from my body and sense of peace and calmness. After two sessions I can say that each session left me feeling uplifted and hopeful. I would definitely recommend sessions with Andrea for whatever situation you may be experiencing."

    - Geneva J., White Plains, N.Y.

    "The session was extraordinary for me. Totally unexpected. I don't want to build up anybody's expectations. Maybe I was just very ready for it. My Reiki treatment involved visual and physical effects, all very positive. So much so, I am now learning Reiki with Andrea. She is dedicated, sincere, and authentic."

    - Ed R., White Plains, N.Y.

    "Although I am a Reiki Practitioner, after some difficult life experiences and transitions, I stopped practicing Reiki on myself and others about 10 years ago. After several recent difficult experiences, I didn't know where else to turn except finally back to Reiki. I prayed to be led to a Reiki Practitioner who would be kind, compassionate and understanding.


    Getting to my appointment proved quite a challenge. But I also felt in my being that perhaps some of the obstacles were signs that this was going to be a very important experience for me... and so it was... Andrea was not only kind, compassionate and understanding, she immediately tuned in to where I was currently on my life journey. During the Reiki session with Andrea, I experienced a gentle healing energy. Towards the end of my session, I had a visual in my mind's eye where it seemed as if spiders and cobwebs had fallen from my mind. It was a very enlightening and freeing experience. As an added benefit of my session with Andrea, I have begun to practice Reiki on myself again."

    - Dawn M., Bronx, N.Y.

    "I had a Reiki session with Andrea and it was an incredible experience. I've had Reiki done in the past and it was no where near as great as this session. I was able to meditate during my entire session and felt extremely relaxed which I didn't think I could feel. "

    - Daniela N., Scarsdale, N.Y.

    "This was my first experience with Reiki and it was both wonderful and restorative. I felt completely relaxed throughout the session. I left feeling both peaceful and energized."

    - Constance S., Elmsford, N.Y.

    "This was my first experience with Reiki and Andrea is the perfect practitioner. Her quiet demeanor is so calming from the first moment. She explains everything about what to expect and answers all your questions. I reached out to Andrea because I was in the middle of final exams and in a state of panic. Somehow she managed to assess my needs and I was able to face my exams without totally falling apart. Normally I have anxiety attacks, but this time, I was ready to face everything with ease. If you're going through any stress or know someone who is - please reach out to Andrea. She can help - no matter what you are going through."

    - Dale C., Yonkers, N.Y.

    "I have been going to Thrive Reiki for the past six months. This is the BEST experience I have ever had with Reiki. The office is quiet and relaxed; a wonderful get-away for me. And I cannot begin to express just how very comfortable I am when I am with Andrea who emits such loving gentleness, kindness, compassion and care."

    - Deborah M., White Plains, N.Y.

    "Andrea was amazing! She made me feel very comfortable and had a great energy walking in. My first Reiki session was so relaxing! I haven't done anything like that before and I'm glad I was introduced. It's a great way to help you relax and clear your head."

    - Julianna M., Mahopac, N.Y.

    “If anyone is looking for alternative therapy that really works, I had the most revitalizing Reiki session with Andrea today!! Andrea is a true gem. If you’re seeking relief from any physical / emotional ailments I highly recommend booking a session with Andrea. I am so glad to have met Andrea. She is kind and compassionate. Not long after meeting Andrea I confided in her about my struggles as a newly single mom and nursing student. Like many of us I live with a great deal of stress and anxiety. When she laid her hands on me I felt an immediate sense of relaxation and peace. It’s hard to describe but during my sessions I feel good vibrations swirling throughout my body. My tension and pain are relieved and the effects are lasting. Now I’m actually planning on booking a session for my children before school starts!”

    - Jennifer S., Elmsford, N.Y.

    "Andrea is absolutely wonderful at what she does: she is professional, very intuitive, great at listening and at engaging with her clients in a non-judgmental manner. I felt light and refreshed after my session."

    - Julia J., Brooklyn, N.Y.

    "Thank you so much Andrea!!!! I have to tell you I am so very happy I found you and your group! Loved the meditation tonight and the practice!"

    - Angela R., Tuckahoe, N.Y.

    "After meeting with Andrea I felt so relaxed. Her energy and personality shine through her smile. She has a wonderful gift and you will feel it the moment you meet her!! Andrea, THANK YOU!!! Can't wait to go back..."

    - Susie C., White Plains, N.Y.

    "Andrea is a loving, compassionate, extremely talented healer committing herself to her craft on a daily basis. My experiences with her, receiving Reiki, have been powerful, helping to push me beyond energetic and personal blocks I didn't know how to get beyond on my own. She has made it her mission to provide accessible services to all, whether that be individual clients or community Reiki Shares. A beautiful soul through and through."

    - Andrew P., Yonkers, N.Y.

    "Andrea has wonderful energy and truly makes you feel so comfortable! She is very welcoming and did a great job. She went above and beyond for us (it was my third Reiki session and my boyfriend's first). Overall it was a wonderful experience and we will be back again."

    - Kat F., Syracuse, N.Y.

    "I had attended an introduction to Reiki at the Crestwood Library. I was so impressed with Andrea's knowledge and training that I decided to schedule a session, which was deeply relaxing. The beneficial effects of the session lasted for several days."

    - Marion S., New York, N.Y.

    "I have loved my session with Andrea. She was attuned to my needs and ensured that I am comfortable. She has a gentle presence and touch that further creates an environment for relaxation and healing. I feel very fortunate to have the opportunity to receive Reiki treatments with her and always look forward to our sessions."

    - Caroline G., New York, N.Y.

    "Andrea is a gifted practitioner. I had two sessions with her and very good results from them. She intuitively sensed where to place her hands and where I needed Reiki most. She spent time before the start of the session assessing my needs and finding out my expectations. She allowed ample time for me to relax and unwind afterwards, asked how I felt after the treatment. What I appreciate most is that this is not an assembly line service. I will be back for a 90-minute session the next time around."

    - Susan Y., New York, N.Y.

    "This place has a wonderful atmosphere and my Reiki session with Andrea was the most relaxing experience I've ever had. She is an absolute professional and at the same time very empathetic and able to feel out the most affected areas of the body. It's a very gentle but effective treatment. I went there for my lower back pain and after hand surgery. I feel that my circulation got much more stimulated and I have an overall feeling of deep relaxation."

    - Annette B., Katonah, N.Y.

    "Andrea is a highly gifted and intuitive Reiki healer. Her warm and healing touch made me completely relaxed. She knew exactly what areas of my body needed attention. The session released a lot of stored emotions that I was carrying for a long time."

    - Manish K., New York, N.Y.
