Dr. Austin completed her Doctor of Physical Therapy degree through Massachusetts General Hospital Institute for Health Professionals. She has extensive experience in pediatrics and is a Board Certified Pediatric Clinical Specialist. Her experience in movement assessment is used to diagnose and treat mechanically induced pain syndromes through postural corrections and precise corrections of motion impairments. She has studied advanced manual therapy techniques in Craniosacral therapy, Visceral Mobilization (organ specific fascial mobilization),Muscle Energy, Neural Manipulation, and Manual Articular Manipulation techniques . 

Dr. Austin started her career at Boston Children’s Hospital working in the Sports Medicine clinic and in the outpatient department working with pediatric orthopedic, neurological and pulmonary patients. After leaving Boston, she worked at Upstate Medical Center in Syracuse, NY where she focused on rehabilitation of clients with spinal cord injuries, strokes, and head injuries. She was the physical therapy consultant in the Spina Bifida Clinic, the Pediatric Orthopedic Clinic, and the Cystic Fibrosis Clinic.

She is certified to administer the Sensory Integration and PraxisTest, has completed Basic, Advanced and Baby Neuro Developmental Treatment assessment and treatment technique courses. Starting in 1990 she has studied extensively with Dr. Jean-Pierre Barral, DO and the late Dr. John Upledger, DO. These Osteopaths have conduct research and have taught mobilization and fascial release techniques involving whole body relationships. Dr. Austin has studied Women’s Health Issues as they relate to musculoskeletal issues, incontinence, and pelvic pain. She continues to refine her assessment techniques of movement impairments, through study with Dr. Shirley Sahrmann, PT, PhD at Washington University in St. Louis, Missouri. 

​Before becoming a physical therapist, Dr. Austin was a physical education teacher receiving her degree at Ithaca College. She has used this background within her physical therapy practice to assess movement dysfunction and correct movement in sports related activities as well as daily living skills. She has coached high school varsity sports including soccer, basketball, and track. Her hobbies include golf, tennis, hiking and biking.

Ms. Dembergh received a Masters in Science in Physical Therapy from Widener University, Chester, PA. Her undergraduate degree was a Bachelors in Arts in history from Haverford College, Haverford, PA. She has studied Spanish extensively and is a proficient Spanish speaker. She has been working at Austin Physical Therapy since 1998 treating children in the home care setting and in schools; and adults in the outpatient clinic. 


Ms. Dembergh loves the challenge of being a physical therapist in a rural setting. She has embraced the need to master a wide variety of treatment techniques needed to treat the varied patient population served by Austin Physical Therapy. Jenny loves helping adults with orthopedic injuries get back to their usual activities. She has a special interest in upper extremity injuries, including: cumulative trauma disorders, hand injuries, and shoulder injuries. She uses gentle manual therapies including Craniosacral therapy, myofascial release, muscle energy and visceral mobilization as a part of hands-on treatment sessions. She is experienced working with children from newborn to teenaged athletes. She has an extensive knowledge of pediatrics treatment including: sensory integration, neurodevelopmental treatment techniques, working with children with autism, cerebral palsy, communication disorders, learning disabilities, and developmental disabilities.

Dr. Miller recently received her clinical doctorate in physical therapy from Upstate Medical University, Syracuse, NY in 2013. She received her master’s degree in physical therapy from Arcadia College, PA in 1990. Prior to that she graduated from Temple University with a BFA in dance, and worked as a dancer, choreographer and certified massage therapist in NJ and PA. 

​Dr. Miller, along with Dr. Austin, recently completed 2 semesters of intensive study with Dr. Shirley Sahrmann at Washington University (2012-2013), focusing on the Movement System Impairment (MSI) Approach to rehabilitation. Results of recent research suggest that using a classification approach to musculoskeletal pain may lead to better outcomes than a more general PT approach. From a thorough MSI evaluation of posture, functional movements and the muscular system, a movement diagnosis is formulated. This leads to an individualized educational approach involving selectively prescribed exercises. Practitioners of the MSI approach generally report a greater degree of improvement in their patients, and the need for fewer treatments than when they used a more general PT approach.

​​Dr. Miller has also been focusing her studies on the neurology of chronic pain. There has been considerable research recently demonstrating the effectiveness of an educational approach to patients (“Explain Pain”), as well as Cognitive Behavioral Therapy for chronic pain. Dr. Miller has studied methods of incorporating both of these approaches into her PT sessions. Dr. Miller has had extensive PT continuing education with an emphasis on gentle manual therapy approaches, including massage, Myofascial Release, Craniosacral Therapy and Muscle Energy. Other areas of interest and continuing education include PT for vestibular/ balance and TMJ issues.  

Besides working at Austin PT, Dr. Miller works with children and adults with developmental disabilities. Formerly, she worked at Catskill Regional Hospital and Center for Discovery, where she developed a strong background in neurological and developmental disorders.

In her free time she loves being with her family, dancing, meditating and travelling.
