Dr. Mark is amazing. She fixed my thyroid, and as my mom was going through menopause, she made her feel 100% better. She specializes in Internal Medicine, Endocrinology, Diabetes & Metabolism… she also travels around the country lecturing on these subjects, so she really knows her stuff. If she happens to be taking new patients and you start to go to her, you NEED to be aware… she doesn’t cut anyone short, so she is constantly running about 2 hours late.
