Since becoming a certified Ondamed practitioner in 2004, Helen O. Hiserman, MHP, PA-C has been working with and treating numerous clients with varied health challenges. The most rewarding work has been with Lyme patients, helping them to achieve a stronger, more resilient immune system to battle their disease.  Ondamed, with its unique biofeedback mechanism, uses the client's pulse to determine what frequency the body needs to improve. Lyme patients can experience detoxification as well as building up their immune system.  This allows healing to occur and opens up other pathways that in turn may need to be unblocked, thus creating further healing potential.  Ondamed can address not only overload of toxic organisms, but focuses on re-vitalizing basic metabolic pathways that can assist in improvement of most health challenges.


Helen, a native of California, has been working in Pennsylvania for most of her PA career.  She received her undergraduate degree in Biology at University of Santa Clara in California and her Physician Assistant certificate along with a Masters in Health Professions from Northeastern University in Boston, MA.  Her background is in Family Medicine, with the last 20 years in Integrative/Nutritional Medicine.  Her work at the Powers Clinic in Williamsport from 1998-2015 focused on addressing functional and lifestyle parameters to treat a myriad of disorders including fibromyalgia, chronic fatigue, thyroid and adrenal disorders, Lyme Disease, cardiovascular disease, and hormonal imbalances to name a few.  She has done extensive nutritional consults to improve wellness using food, not medications.  She has consulted with numerous clients for weight loss, and overall improvement in health and well-being. She is well-versed in the HCG protocol for weight loss and familiar with a variety of diet protocols.  During her tenure at the Powers Clinic she received certification as a Colonic Hydrotherapist and Ondamed ® practitioner. 

Helen is an active member of the Pennsylvania Society of Physician Assistants having served as Secretary and currently is the Awards Chair.  She is an avid gardener, growing her own produce. A mother of three, Helen continues to homeschool her youngest child and volunteers with Family Promise in Williamsport.  She enjoys playing piano and is currently a substitute organist for various churches in the area.  She loves to read, especially mystery novels and thrives on gluten free cooking and baking.
