Nicolas Barton, PT
Physical Therapist

I am a Southern California native, and grew up in the San Fernando Valley of Woodland Hills. After graduating from El Camino Real High School in 1981, I attended Pierce Community College working in the Athletic Training room, treating and taping the Football and Basketball Teams, and pursuing my Associates Degree in Science, with a state licensed certificate as Physical Therapist Assistant-PTA. I graduated in 1985, and began my career working with Kaiser Permanente in the acute hospital and out-patient clinical settings, for approximately 3 years. Following this, my interest started in the private sector of medicine, working for many great out-patient therapy settings to learn as much as I could in the field. I had interests in orthopedics; specializing in post-surgical rehabilitation; total joint, and sports medicine. One clinic was post-surgical foot and ankle therapy, another hand rehabilitation, then one specializing in spine, and this is where I wanted to know more, in learning about manual therapy specialties in treating the spine. I worked for another 3 years, and then decided to go back to further my education. I then went on to complete my Bachelors Degree in Health Education, in 1997, from Cal State University Northridge, and following this, on to complete my Masters Degree in Physical Therapy, graduating from Loma Linda University, in 2000. My philosophy is to treat the whole individual; mental, spiritual, and physical, and include all these aspects of the person in their rehabilitation. I am a manual therapist, specializing in manual techniques to enhance mobility, and encourage return to that individuals goals in returning to their previous level of function, recreational activity, or sport. I have been privileged to work in a field that I love, and enjoy what I do each day.
