• "i have had an incredible transformation journey with andrea." - Tyler s.

    Are you tormented by anxiety and stress?

    Looking for support (and relief) during times of crisis and overwhelm?

    A different approach to make you feel better and keep you sane?


    I know first-hand how debilitating and all-consuming stress, overwhelm, and anxiety, is.

    This gnawing sense of everything is too much can be like living hell. But you are not alone.

    You can feel less tense, be more balanced, peaceful and even joyful.


    My clients feel lighter and better with hands-on treatments, mindfulness practices and consistent support.


    Their stress levels and feelings of overwhelm decrease - and their outlook on life improves.


    They become more balanced, focused, and at peace, which makes life (and all its challenges) easier to deal with and sets the foundation for personal (and professional) success.

  • what to expect

    Rooted in the belief that to heal means to make whole,

    Reiki practice addresses body, mind, and spirit.


    Reiki is a system of natural healing from Japan that is based on mindfulness practices and light touch. Sessions help promote relaxation, stimulate the body's innate healing response, and support personal development.

    Reiki helps us become and be more aligned

    with the flow of life and our nature.


    A natural, non-invasive healing practice, Reiki sessions stimulate the body's relaxation and self-healing responses through the light touch of the practitioner’s hands. In addition to improving overall health and well-being, people turn to Reiki when coping with life’s stresses as well as for support during health and emotional challenges and medical treatments.


    Recipients and practitioners have reported:

    • A more positive outlook.
    • Better ability to deal with anxiety and stress.
    • Decreased pain.
    • Easier breathing.
    • Improved sleep.
    • Increased focus and concentration.
    • More clarity.
    • Feeling like themselves again.


    Reiki sessions always take place with the recipient fully clothed on a massage table. There is no pressure, manipulation or massage, and sensitive and intimate areas of the body are never touched. Please note that Reiki is no substitute for conventional medical or psychological care. There are no claims or guarantees of healing or curing disease.


    Benefits of Reiki sessions and training:

    • Stress relief and management.
    • Increased relaxation.
    • Increased sense of balance.
    • Overall well-being and a sense of peace.
    • Better ability to deal with life’s challenges.
    • Physical and emotional resilience.
    • Clarity.


    My mission statement: To present, practice, and teach Reiki as a safe and credible healing modality that promotes relaxation, mindfulness, well-being, and resilience.

    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 state of being, a way of life, a way of well-being that I am committed to share with others. Would you like to find out more? How about we have a little chat? Or if you want to get to me know me a bit, join me on Instagram or Facebook (@thrivereiki).

    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).

  • Client case: Insomnia, anxiety and 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."

    Client case: 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. After each session he says that he feels like a better man.

    Client case: support during and after cancer treatment

    Female client, 50, 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.

    Client case: chronic neck pain and feeling stuck

    Male client, 50, entrepreneur


    Regular Reiki sessions help him feel nurtured and taken care of. They also supported him when he made the move from full-time employment to entrepreneurship.

    Instead of pushing himself all the time, he now experiences more compassion and time for himself and with his son. He also feels like himself. He says he really like this guy and now has the creativity to help him solve problems.

    Client case: anxiety and low self-esteem

    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. When she was finally able to relax, she was also able to conceive, something that she had been wanting for a long time.
