Mary Estonactoc (CMT)

I am a certified massage therapist with over 900 hours of training from National Holistic Institute and the Body Therapy Center in Palo Alto. I am also a stretch and Reiki practitioner. I have been practicing massage since 2016. After 20+ years in corporate HR, I found myself at a crossroad. I became my mother’s caregiver and looked for less stress and more flexibility in my next job. The timing was right for me to change careers and so grateful that I found massage therapy. My desire and passion is to promote balance and harmony for the body, mind, and spirit through massage and bodywork. The human body is amazing and has the capacity to heal itself. Nurturing therapeutic massage and balance of energy flow can help facilitate this healing.

I always strive to deliver effective treatments that provide relaxation, pain relief, greater flexibility and range of motion. When the nervous system is relaxed, the muscles follow. The body begins to restore itself and we feel renewed and rejuvenated.

When I’m not practicing massage I love to tend to my garden of organic herbs and vegetables and spend time at the ocean. I also enjoy listening to my musician husband perform.

Sherice Hamlin

Born and raised in the Bay Area, I've always had a deep connection to my community. My passion for helping others led me to pursue a career in massage therapy, graduating in 2008.

With a strong foundation in anatomy and physiology from my pre-med studies at Cal Poly San Luis Obispo, I specialize in deep tissue massage. My goal is to alleviate pain and improve overall well-being through targeted, therapeutic techniques.

Outside of my practice, I enjoy exploring my creative side through sewing Renaissance costumes, tending to my bees and cats.

As I continue to pursue my dream of becoming a medical doctor, I am dedicated to providing compassionate and effective care to my patients.

Wendy Lai

With over 10 years of experience, I've honed my skills in relieving tension and pain, particularly in the neck and shoulder areas. I specialize in deep tissue therapy. I'm committed to creating a comfortable and relaxing session for my clients.

When I'm not working, I enjoy spending time with family, indulging in homemade pho, and listening to soothing jazz.

Michael Nguyen

I graduated in 2004 from Trinity College School of Massage and have extensive experience working in chiropract offices. My specialty resides in alleviating shoulder, neck, and back pain with the use of deep tissue and acupressure work. Each session is customized to fit the needs of individual clients. I am well aware of chronic pain due to sitting in front of computers for long periods of time, as I was a mechanical engineer for years. I entered the massage therapy field initially to benefit myself through therapeutic touch. I am now pain-free and passionate about helping my clients improve their health and levels of activity.

​​​​​​​When not doing bodywork, I especially enjoy spending time with family, as well as fishing with friends.
