GLENN ALLEN BEFORE AND AFTER
Glenn Allen - Before & After

“Amazing!!! I have lost 29 pounds in 5 weeks and I do not feel like I am depriving myself. This is definitely a diet that I can sustain for a long time. The doctor is very knowledgeable; I used to take three different medications for diabetes but now I am completely off all three! And my blood sugars are completely normal!

I would definitely recommend this program to anybody looking to take control of their health.”
— A.W.

“An absolutely wonderful experience! Dr. Hevi is not like other doctors. He is not a drug happy mechanic but offers a more holistic approach to medicine. And I like that. He listens to you. And he genuinely cares. He gets to know you and that’s the best approach to treating you.

He is a wonderful person to be around, great sense of humor, and his office staff are a true delight.”
– Alex W
My husband, son and I have been primary care patients of Dr Hevi since December and have been very pleased with him. We have been to the office many times between the 3 of us and he always takes his time and listens carefully to any concerns. His knowledge on nutrition is excellent and helpful. His nurse Frankie is super friendly and is great at making us feel at ease. If we are sick, we get in that day. We all highly recommend Zenith!
– Laurie Haines
Getting older and having all types of gut and food allergy issues. Doc helped me reset my body. Knowledgeable, cool, funny. Highly reccomended. Thanks!
– Chris Harrison
Dr. Hevi is a very caring, unique, talented doctor. He takes a “holistic” approach to medicine and looks at every possibility to help you “heal”. He doesn’t just write you a prescription to treat symptoms- he will take you on a journey to heal. Magnificent Doctor.
