Jason Garcia


Jason, often known as the “massage guru” at Psoas, began his journey with massage in 1997 at the prestigious National Holistic Institute in Emeryville, California. He immediately gravitated towards learning about more challenging clinical situations and was soon asked to mentor with one of his instructors, Erik Beavers. For the next 2 years, a passion for trigger point, myofascial release and deep tissue skills was born and honed, working at the Recreation Center for the Handicapped. These abilities, combined with in-depth assessment and superb listening skills, allows Jason to customize each session to meet his clients’ needs. Since 2005, Jason has taken an interest in neuro-scientifically based techniques. He became a certified Feldenkrais practitioner in 2009 and a NeuroKinetic Therapy (NKT) practitioner in 2011. His emphasis on the brain’s ability to make changes and adapt to new patterns of movement has given him a unique insight into clinical conditions. By seeking the root of the problem, his clients enjoy long lasting results. Jason joined the Psoas team in 2006 and immediately knew he had found a home that shared his passion and high standards for massage. He is extremely versatile and considered an expert, whether his client is pregnant and dealing with low back issues, a desk worker troubled by carpal tunnel syndrome, a professional athlete sidelined with recurring knee pain or just normal Joe/Jane looking for the best deep tissue massage they have ever had. He is considered a senior therapist at Psoas. With over 1,800 hours of training and over 20,000 hours of massages under his belt, Jason is one of the most experienced practitioners in the Bay Area. His education, skill, and experience, combined with a teaching and public speaking background, made Jason uniquely qualified for his promotion to Clinical Education Supervisor at Psoas. He works closely with Psoas therapists in their ongoing growth and development as practitioners. Jason is happily busy with his wife Melanie and three daughters Kylie, Amelia and Liliana. He continues to teach both new practitioners and advanced workshops in sports and clinical massage to seasoned therapists around the Bay Area and enjoys shaping the future of the profession. He has thoroughly enjoyed his work since day one.

  • Clinical Deep Tissue

D Bacome


D’s passion for bodywork began at the young age of seven, when their grandparents’ complaints of shoulder soreness and painful headaches inspired them to massage their grandparents until they felt better. When their grandparents remarked that their discomfort continually decreased, D was so thrilled with their recovery that they dedicated themselves to therapeutic bodywork from then on. Viewing bodywork as a direct way of improving peoples’ quality of life and reducing the causes of discomfort and pain, they focused their training, assistant teaching, and extracurricular studies on structural, neurological and movement-based bodywork methods.  They graduated from the Sierra Massage School in 2006, the San Francisco School of Massage in 2009, and the California Institute for Bodywork Education in 2010. Inspired by the pain reduction their family achieved, D began a blend of sports massage, deep tissue, and myofascial therapy in 2010, working primarily with people who had pain, injuries, and soreness that had not been successfully treated by other professionals. In 2016, D became fully certified in Active Release Therapy (A.R.T). Using a blend of sports massage and deep tissue that’s greatly informed by intensive study in fascial release, physiology, and neurological bodywork or full A.R.T sessions, D has had great success in helping athletes and people in ongoing pain and discomfort find relief and increased performance through massage. By actively listening to each clients’ needs and asking about their daily activities, their attention to detail and knowledge of the interconnectedness of the body, along with their integrated style of bodywork, allows them to catch and retrain subtle movement patterns that keep people in pain, and perform deep tissue that addresses soreness and discomfort while treating their underlying causes. This attention to detail and passion for truly therapeutic work led them to be selected as a sports massage therapist for the America’s Cup Oracle Racing Team in 2012 and 2013. They bring this experience and 4 years of clinical bodywork experience treating pain and movement imbalances to their sessions. An avid swimmer and hiker, D loves to explore natural spaces in the city and find new running trails.

Some of D’s specializations include:

  • A.R.T. (Active Release Technique)
  • Myofascial Release/ Structural Integration
  • Muscle Energy Technique
  • Acute Injuries
  • Repetitive Strain Issues
