Professional Philosophy

Jonna is a physical therapist, who has over 25 years of experience working with neurological, orthopedic, pre/post partum, sports injury patients as well as private clients in the area of fitness and Pilates. Her recent area of expertise is manual orthopedics of the spine and extremities with emphasis on muscle energy techniques and functional core therapeutic exercise.  She owns Central California Physical Therapy Specialists as well as a Pilates based fitness center, called Integrated Fitness.She believes that physical therapists/assistants can offer the best care in helping patients resume pain free movement patterns at all levels of function.   Her favorite exercise is bridging and her goal is for patients it to be able to get out of a chair or off the toilet with no help! “I have always worked in direct patient care and love getting my hands on people.  As a society we are less mobile than ever and it is my goal to reverse that aging process by keeping patients mobile and strong so we don’t have any ‘death by sitting’”. She has accepted the position of Program Director to develop Physical Therapist Assistant (PTA) Program at the College of the Sequoia.   Her goal is to give back to the Physical Therapy profession by training students to find a meaningful career in providing quality care to patients.  Jonna most recently completed her Ed. D with the focus of her research on how to predict the pass rate on the NPTE for PTA applicants.

Academic Coordinator of Clinical Education (ACCE)

Professional Philosophy​

Tatiana is a physical therapist with over 18 years of experience working with patients with neurologic and orthopedic injuries as well as the rehabilitation of athletes.   She emphasizes thorough, whole body analysis to design individualized care and approaches all patients from the perspective of performance enhancement.  She integrates manual therapy with principles of motor learning and exercise science.   “I had a martial arts professor tell me once ‘Practice doesn’t make perfect, perfect practice makes perfect.’  This has always stayed with me.  It doesn’t mean you have to be perfect, but perfection should be what you strive for; to continue to grow and learn.  My goal is that I never see a patient again for the same diagnosis.  If I do my job right, I will impart what they need to know to continue to go on without me.  I view teaching in the same way.”  She accepted the position of Faculty/Academic Coordinator of Clinical Education to share her passion for the profession of Physical Therapy by helping to develop professional, ethical, exceptional physical therapist assistants.  In her spare time, Tatiana loves to teach and train in Martial Arts, ride horses with her daughter and invent new recipes.
