Bruce is one of our Licensed massage therapists offering patients a chance to combine the benefits of Non-surgical spinal decompression with Cold Laser, chiropractic with massage and Rehabilitation Services. Bruce is Nationally Certified in Non-Surgical Spinal Decompression from Parker University.

Bruce’s loves softball-coaching, football, basketball, full body fitness in reality he has done them all. If he has not participated in your sport he most likely has worked on its most common injuries. The prime purpose of sports massage therapy is to help alleviate the stress and tension, which builds up in the body’s soft tissues during physical activity. Whether one is an athlete, or a desk jockey, minor injuries and muscle tension occur, due to overexertion and/or overuse. Massage aids in recovery and repair of these tissues. Above all, sports massage can help prevent those nagging minor injuries that so often get in the way of optimum performance and achievement. This treatment is not just for the athlete: anyone can benefit from sports massage, including people in physically demanding jobs and those not quite so obvious (occupational, emotional and postural stress may produce many similar characteristics to sports injuries)

Bruce’s experience includes working with the training staff therapist to the Portland Timber Soccer Club and with the Portland Monarchs Football Club performing pre-event and post- event treatment massage on players. He has experience with injuries such as rotator cuff injuries, whiplash, tendonitis, patellofemoral syndrome and many other postural dysfunctions.

Bruce is dedicated to personal wellness. His healthy living is reflected in his calm presence and strong hands. His massage style combines gentle specific stretches with direct focused strokes to release areas of tension and dysfunction. He uses techniques such as Myofascial Release, Thai, Sports Massage and Neuromuscular Therapy to restore optimum function and movement throughout the body. Bruce views the body as a whole with the goal of symmetry and balance, which are essential to health and well-being.

Bruce graduated from Everest College with honors in Vancouver with an emphasis in sports and treatment therapy. Bruce loves to spend time with his family, which are his spouse Jane to whom he has been married 31 years, and has four wonderful daughters Annie, Jill, Kelly, and Kristin, five cute grandchildren, and two awesome big dogs.

For 30+ years Lisa has been in either the hotel industry or in the healthcare field. Being present and accommodating guests or patients is responsibility she takes to heart. Her two major role models in her professional life taught her integrity, commitment, discipline, and compassion.

In Lisa’s time away from the office you could find her sitting in a favorite coffee house writing, exploring the PNW region-indoors or out, sharing a meal and conversation with her close friends & 2 children, or curled up under a blanket watching a documentary. She also has a love for supporting locally owned businesses and is all too happy to try out something new and different on the Westside.

Some of her past and present volunteer contributions have been: Restorative Community Service mentor at Clark County Juvenile Court, Friends of Trees, Stone Soup Community Meal, Fruit Valley Neighborhood Association, and the Free Clinic of SW Washington.
