When I came to Dr. Stengler I was diagnosed with fibromyalgia. The doctor I was previously seeing had no answers for me. Dr Stengler ran the right tests, found out the underlying cause, and a year later I’m so much better. While searching for the cause of my fibromyalgia he discovered that I have the 5 MTHFR gene mutation. While this wasn’t involved with my fibromyalgia, it can be serious, and because it can be passed to family members, we were able to all be tested. I’m so grateful for his knowledge and truly caring nature.
