Dr. Erin Isanhart PT, DPT, NCS

Advanced Vestibular Physical Therapy Certification

San Francisco 49er's Team Consultant

University of Pittsburgh Adjunct Associate Professor


I would first like to extend a warm welcome to you. My name is Erin Isanhart, I am a Doctor of Physical Therapy, and I specialize in Vestibular & Concussive Disorders. 

Remembering the doctors of years past who made “house calls,” I wondered why we couldn’t still do that.  Why shouldn’t therapists like me once again carry their practice back into people’s homes?  In that moment my present practice took on a new look with a new clinical setting, i.e., my patient’s homes.  The “house call” has returned!  My reintroduction of a tried and true practice setting has been welcomed by many who are now enjoying my personalized care in the relaxed comfort, safety, and familiarity of their own homes.

Since receiving my Doctor of Physical Therapy degree from the University of Pittsburgh in 2008, I have been actively practicing my healing skills with the neurologic population.  After graduation, it was my privilege to begin my work at The Centers for Rehab Services, which operates in partnership with the University of Pittsburgh Medical Center.  Vestibular and concussive pathology intrigued me, and as such, I decided to sit for the Emory Competency Certification in Vestibular Therapy, a test that only few are invited to attend, and further are able to even pass. I successfully passed the competency and became a vestibular rehabilitation specialist in 2010.  In 2014, I went on to qualify to sit for the American Board of Physical Therapy Specialists Neurology Exam. This test is one of the most rigorous tests in the field of physical therapy, as 50% of those chosen to sit, will pass. After extensive preparation, I sat for the test, and successfully became a Board Certified Clinical Specialist in Neurologic Physical Therapy.  In April 2022, I passed the University of Pittsburgh Advanced Vestibular Physical  Therapy Certification. 

During my time in the Bay Area I worked exclusively at Stanford Health Care with Vestibular and Concussive Disorders, and was one of the founding members of the Stanford Concussion Clinic. In addition, I collaborated with the Rehabilitation Medicine team at Stanford Children’s Health and Stanford University Athletics to enhance their respective concussion programs.  I served as adjunct faculty for the Stanford Geriatric Physical Therapy Residency and the clinical expert to the Orthopedic Physical Therapy Residency. 

I had the absolute honor to present my clinical knowledge and understanding of vestibular and concussive disorders on behalf of Stanford Health Care and into the broader community in collaboration with the California Concussion Institute over the years. I continue to collaborate on the California Concussion Institute Advisory Board.

The next chapter of my story of service is yet to be written by you, my patients.  At your invitation and convenience, it would be my pleasure to bring my personalized service in vestibular therapy to your home.  The story continues.

My Practice: FAQ


In a cash-based physical therapy model, the physical therapist enters a contract with a patient to provide services to meet their goals.  The patient pays at the time of service via credit card, check, or cash.
The patient will be provided a detailed bill with the appropriate CPT codes used if the patient choses to seek reimbursement from their out-of-network benefits.     
Documentation of the evaluation and treatments are performed just like any other physical therapy clinic with legal compliance.


Most insurance companies will provide payment of services received out-of-network.  Going out of network means you can choose to see a physical therapist who is not a participating provider with your insurance company.  It is encouraged to contact your insurance provider to know their reimbursement of services.  In cash-based services, it is the patient who is waiting for reimbursement rather than the provider.


The initial evaluation is 75 minutes.   This time is reserved for you.  Once your initial appointment is set, you will receive new patient forms. Please fill out these forms prior to your appointment to not impede on your session time.  Follow-up visits are 60 minutes.
