Frequently Asked Questions (FAQs)

We’re looking forward to working together to help you achieve your health goals.

  •  A focus on Integrative and Functional Medicine. We are specialists. We reverse illness by focusing on what we do best, Integrative and Functional Medicine. This means that you will keep your primary care provider outside of our office for acute illnesses and preventive visits like well child exams, annual exams, and screenings. This allows us to focus on the root cause of your issue(s).

“This group of health professionals and their support staff are incredible! It took over 20 years of misdiagnosis and harmful treatments before I found [the Hirsch Center]. 2 years and I feel more in control of my health issues than ever before.”

-Pati K.

  • Long appointment times. 100-minute new patient appointments and 50-minute follow-up appointments. Longer doctor’s appointments give you and your provider the time needed to make sure that you are heard, that all of your questions are answered and that you leave with a clear treatment plan so that you get the best results possible.

“I appreciate how well you listen and give feedback/support. I feel like I am really listened to and treated as a whole person, not just a symptom!”


  • Awesome, cutting-edge therapies that work to speed up the healing process. We use lifestyle modifications, top-of-the-line supplements, IV therapy and Sauna therapy to get you better as fast as possible. In the coming months, we will add Low Dose Antigen Therapy (to resolve food and mold allergies), Low Dose Immunotherapy (to reset the immune system-infection relationship), PEMF (for pain and improved circulation and nutrient absorption), HeartMath (for stress and sleep) and bio-meridian therapies (to reset your body’s energy fields (meridians).

“During the prolozone treatments, I’ve seen a dramatic improvement in what I can do with my knee . . . now it’s much, much improved. I can do things I couldn’t do before.”

-Micki M

  • Customized, individualized plans for every patient. Everyone is different and requires different treatment plans. We gather all the data we need to treat you as an individual.

“[The Hirsch Center] accepted me as the unique individual person I am, with respect. I feel I have a partner in my health choices.”

-Heather Z.

  • We utilize the most advanced laboratory testing to determine the true causes of your medical problems. By using functional medicine laboratory testing tools and techniques we can get down to the cellular level to figure out where the problem is. We also use preventative laboratory and genetic testing to determine your risk of having future medical problems (like a heart attack, stroke or Alzheimer’s).

“I was a mess when I first saw Dr. Hirsch. My many issues had been written off by several doctors as “normal”, and I had almost given up hope for a healthy life. Dr. Hirsch listened, really listened, and agreed that my troubles were indeed not normal, and he jumped to action to help. We’re still “peeling the onion” that is my many-layered health situation, but I cannot believe how improved I feel most days. I have hope again, and have a wonderful support system.”

-Leah J.
