Dr. Mesmer is always on point- very professional, caring, and knowledgeable about my health history. My only comment is that I was about 10 minutes late to my appointment that day, and I felt the visit was a bit rushed so she could stay on schedule for her next patient. I understand this wasn't her fault, but I do wish I had a bit more time, especially since it was my annual physical. That said, Dr. Mesmer usually takes the time needed during each visit, and this was the only time I felt slightly rushed. She's an exceptional provider, and I'm very grateful for the care she provides.
