Chiropractor | Owner

Dr. Clark Pitcairn started his journey in chiropractic as a patient. At the age of 7, he received his first chiropractic adjustment. In turn he remained a patient due to the profound changes it made in his life. As a child, Dr. Clark had a chronic upper respiratory problem. His cough was so bad that it became a bit embarrassing for him in grade school. After starting chiropractic treatments, his cough began to lessen and eventually went away completely. Due to that care, he was able to run around and play sports with all the other kids without wheezing. His mother saw the benefit of having her kids under regular care so she made it a priority for all three of her children. As a result, today, Dr. Clark and his two sisters are all chiropractors.  Dr. Clark’s interests include hiking/backpacking, rock climbing, snowboarding and surfing. He currently lives in NE Portland with his beautiful wife Julia and four wonderful children Dylan, Brody, Micah and Tanner.

Christina Fitzgerald

LMT # 24286 CA #5640

Christina learned massage at the Oregon School of Massage in Portland, Oregon and the Aloha Massage Academy on the Big Island of Hawaii. She came to the healing arts via a circuitous route, after deciding that a BA in music and the life of a classical music rock star wasn’t financially stable, and absconding from a master’s program in library science. An apprenticeship in herbal medicine and ethnobotany, certification course in nutritional therapy, classes in Core Synchronism, QuantumTouch, Biodynamic Craniosacral therapy and many years of massage school later, she ended up doing massage on a beach in Hawaii, and acclimating Iron Man triathletes to the pending rigors of their grueling competition.
She has now made her return to the rainy skies of the Pacific Northwest, because she missed the rain. (Kidding!) But jesting aside, the healing journey is a very personal one, and if you have any serious questions, please ask!

Billie Melchor

LMT # 21609 CA 5348

Billie graduated from East West College of Healing Arts in Portland, OR. Her unique and integrative style combines several modalities, including: Swedish, deep tissue, cranial sacral, myofascial release, prenatal, trigger point and structural integration techniques.

Her belief is that through time, due to life activities, physical and emotional trauma, surgery and illness, the human body slowly develops misbalanced and incorrect posture which eventually leads to discomfort, pain and injury. Her focus is in identifying these postural deviations and correcting and realigning the body, allowing the client to move pain-free and with greater ease of motion. When the structure of the body is in proper alignment, less energy is spent in the muscles fighting to regain balance, allowing for higher function in all other systems of the structure.

She also works with motor vehicle accident injuries, sports injuries, post-surgical rehabilitation, sciatica issues, thoracic outlet syndrome, frozen shoulder, TMJ and rotator cuff issues. The more generalized “relaxation” deep tissue work helps to integrate and compliment the chiropractic work also offered at the clinic.
