Patient Reviews
Jan 07, 2020
Dr. Merker is an excellent, knowledgeable, and experienced doctor. He recently leveraged his decades of experience to recommend and perform a colonoscopy. Other doctors would not necessarily have done this, due to my relative youth. He found both a polyp and colon cancer, thankfully very early. This could have saved my life, because under normal circumstances I wouldn't even have had a colonoscopy for 9 more years. He is also an excellent primary care, and takes the time to call very frequently to help me through my care.
