"My whole family has benefited from Dr. Siegel with BioHealth! In short, after not getting answers to our health issues along with being handed prescriptions that did not fix our problems, we sought out Dr. Siegel after a couple of referrals. We finally got answers! After clearing out the toxins, we could step into thriving with much better health overall."

"I have no doubt that BioHealthOhio saved my life...more than once! I've been working with Dr. Siegel for just over a year and though I have many auto-immune issues, I feel I've just about overcome most of my health issues now. My fibromyalgia and crohn's have settled down and my body feels almost normal again--after 35 years of pain."

"Dr. Siegel is so knowledgeable and such a caring person. We have been looking for answers for my son's illness for almost 4 years, every appointment resulting in dead ends. We saw Dr. Siegel and what he found was astonishing. For the first time in years, we have REAL HOPE! I can't even describe how good that feels!"

"Dr Siegel and his staff mix genuine caring, sharp knowledge, and a beautiful energy into everything they do. I knew I was in the right place at my first appointment, and I felt I was genuinely heard for the very first time. Being in their care has lifted such a burden from me. Thank you!"

"My first appointment, I cried because I was so relieved with what Dr. Siegel was able to diagnose. I was terrified going in that he might not have an answer for me either. I will follow Dr Siegel's advice to the moon and back. I thank God everyday that Monica shared the information with me that lead to my first visit."

"I am so happy that I went to see Dr Siegel. I do not even want to think of the path I was going down. Every Doctor was saying synthetic hormones. I am 37 and everything I had read was making me so scared of the side effects. He is so full of knowledge and takes his time with you. I feel like I understand myself more. I cried tears of joy on my way home."
For over 40 years, Dr. David Siegel has been dedicated to providing exceptional care to his patients. His practice has grown steadily through personal referrals and word of mouth, a testament to the trust and satisfaction of those he serves—without relying on paid advertising.
Our Patients mean the world to us
The key focus of our approach is to assess for and treat “Energetic Debt.” Energetic Debt is when your cells are no longer able to produce adequate energy (i.e., ATP) to effectively run your body’s daily activities. As a result, dysfunction and subsequent disease will then occur. Addressing “Energetic Debt,” therefore, is the most important factor when it comes to improving and/or solving most peoples’ health issues, no matter how complex.
