I have been going to this practice for several years, but this was my first year with Heidi Flagg and I will only be going to her from now on. She was so incredibly kind and saw me within five minutes of entering the office for my annual visit.

I could not recommend Dr. Flagg more, she always makes me feel so comfortable, and even though I only see her once/year, she remembers things about my job or other things I've told her. She truly cares about her patients, and I actually look forward to the appointments!

Dr. Flagg is very calming, strong and simultaneously forthright. She is not quick to lean on any one solution definitely and explores all options. Her approach to peri menopause/menopause is refreshing and based on trying organic remediesto start if you so choose. She is patient. I’m deathly afraid of doctors and she is not judgmental or insistent.

The front desk had no idea what they were doing and it took forever for them to figure out how to process my basic information. Because they took so long, my appointment with the doctor didn't start until 40 minutes later,at which point she was clearly annoyed and made it seem like it was my fault. She was fine, but I'll probably find a new place for next time.
