I am so thankful and grateful that I have found Holtorf Medical Group. Dr. Evans and the entire team there is so helpful and so kind. They are so thorough and take the time to go through results, tests and best next steps. So happy to be a part such an incredible group of people.

Holtorf Medical Group is amazing! I have been going here for years (9!) and I could not recommend it more. The drs listen and evaluate a wide variety of markers to ensure the best protocol is followed. I have found other endocrinologists to be far too narrow in their scope of care, and would recommend Holtorf (specifically Wightman or Evans) to anyone in need of a more tailored approach.

I’ve been seeing Dr. Whiteman for help with chronic pain and thyroid issues, and I couldn’t be more grateful for the care I’ve received. He is incredibly knowledgeable, thorough, and genuinely committed to finding solutions that work. For the first time in years, I feel heard and supported by a doctor who truly understands what I’m going through. Dr. Whiteman takes the time to explain everything clearly and never makes me feel rushed. His guidance has made a huge difference in managing my symptoms and improving my quality of life. I highly recommend him to anyone looking for a compassionate and skilled physician.
