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
  • Feldenkrais
  • NKT & PDTR

David Bacome

David’s passion for bodywork began at the young age of seven, when his grandparents’ complaints of shoulder soreness and painful headaches inspired him to massage them until they felt better. They remarked that their discomfort continually decreased, and David was so thrilled with their recovery that he dedicated himself 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, he focused his training, assistant teaching, and extracurricular studies on structural, neurological and movement-based bodywork methods.  He 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 his family achieved, David 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, David 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, David 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, his attention to detail and knowledge of the interconnectedness of the body, along with his integrated style of bodywork, allows him 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 him to be selected as a sports massage therapist for the America’s Cup Oracle Racing Team in 2012 and 2013. He brings this experience and 4 years of clinical bodywork experience treating pain and movement imbalances to his sessions. An avid swimmer and hiker, David loves to explore natural spaces in the city and find new running trails.

Some of David’s specializations include:

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

Sarah Day

Since 2003 Sarah has been facilitating the balance, awareness, and ease of clients through hands-on bodywork and movement education. Sarah’s sessions are tailored as collaboration towards each clients optimal desired potential. She compassionately integrates structurally oriented Deep Tissue massage, functional alignment balancing, and Myofascial Release with Swedish massage and subtler modalities. Her bodywork emphasizes a respect for natural biomechanical design and encourages an approach of loving-kindness for one’s body. Sarah also offers Lymphatic Drainage work, as well as caring Pre & Postnatal massage. Having studied with an array of wonderful faculty at the Monterey Institute of Touch in Carmel Valley, she continued her training at Twin Lakes College of the Healing Arts, took clinical anatomy courses, and invested many years in studying biomechanics for dancers. She spent the first years of her massage practice teamed up with a PT and chiropractor, experience that provided a basis for addressing specific issues such as carpal tunnel, tendonitis, plantar fasciitis, tension headaches, structural imbalances, and working with myofascial restrictions from both patterns of use and from scar tissue. A Certified Axis Syllabus Teacher, Sarah brings to her work a background in dance and movement arts, many years of experience that deeply inform her approach to bodywork. Her first hand understanding of the body in motion has been an asset in caring for clients, whether they be athletes or individuals looking to feel more at home in their body. Gleaned from this training, some of the elements that inform Sarah’s approach in massage sessions include:  functional alignment principles, healthy joint parameters, training the body for multi-planar activity, the mechanics of weight distribution, and the ways in which the body generates and harnesses kinetic potential for dynamic situations. Sarah would love to assist you towards your personal wellness goals, whether addressing chronic, acute, or repetitive stress pain conditions, expanding your movement capabilities to deepen into your particular embodied practice, or simply creating space for the innate wisdom of your body to flourish.

Cheryl Martin

Cheryl is a seasoned bodyworker with over 20 years of experience. She uses a multidisciplinary approach to bodywork. While listening to the tension strain patterns in the body with her sensitive palpation skills, she utilizes slow sustained pressure with gentle stretching and movement techniques within a session for increased effectiveness. In addition to treating symptoms, Cheryl likes to follow clues within the tension patterns of the body to find the source of the strain, releasing restrictions to free the body from pain and limited movement. Like many bodyworkers, Cheryl was inspired to study massage therapy while recovering from multiple injuries of her own and a life-long fascination with how the body works and the interplay between form and function. She studied at Body Therapy Center in Palo Alto, CA (now the McKinnon Body Therapy Center in Oakland, CA) from 1994-1997. The three-year program consisted of a strong foundation in Clinical/Deep Tissue Massage, Pre/Postnatal Massage, Sports massage, and advanced techniques in Trigger Point and myofascial release. In 2000 Cheryl continued her education at the Upledger Institute studying CranioSacral Therapy, the Barral Institute for Visceral Manipulation, and Foothill College in Los Altos, CA studying Anatomy & Physiology, Athletic Conditioning, Injury Prevention & Recovery, PNF Stretching, Athletic Training and Periodization, earning a Personal Training Certificate in 2009 and an A.S.

You can usually find Cheryl enjoying the great outdoors, exploring somewhere on a bike, hike, or walk around the Bay Area. Nature is her sanctuary. Cheryl also enjoys travelling. To her, spending time along the banks of the Narmada River in Gujarat State, India, is one of the most peaceful places to fortify a simple, healthy lifestyle and be in rhythm with nature.
