Breakthrough Your Recurring Symptoms- The Steps

I just want to thank you again for giving me something to live for. When I first came to see you, I felt like a slug. I had NO energy at all. My mouth was sore with thrush, and I felt as though I was of no use to anyone. Thanks to your and your staff, and loving care, I am now a different person. 



ll have looked a long time to find a doctor like you. I’ve tried top get in shape but was told to eat all the wrong things. You taught me right and I lost 40 pounds. I am 50 years old but feel like I’m 25.

You not only healed my body, but my mind also.



I fell so fortunate to have made my first phone call to Dr. Petro’s office seeking help with physical ailments that continued to tax my tolerance level and rob me of the joy of living. I was amazed by Dr. Petro’s ability to identify the underlying problems. For the first time, a doctor that really listened and made a genuine effort to map out a road back to better health. It wasn’t just because “I was getting older!”



What Makes Our Healing Process Unique?

Our Health Restoration Program looks at defining why a individual’s health is not functioning properly. This is done through specific testing including revolutionary microbiome and genetic testing not looking at what specific diseases a person might acquire but rather what are the genetic variations that can be limiting optimal health. Once we have a clear picture of the limitations a plan is developed to upregulate the suppressed systems leading towards regaining optimum health.

What’s Waiting Another Day Costing You?

How long do you want to keep guessing at how to get better?
