All my interactions with this practice has been excellent. I've received good advice as to what was needed, and agreed. I feel better than I did for some time, so the treatments I received were beneficial. Follow-up has been excellent, and I am very pleased

Dr. Hahm was spectacular: extremely knowledgeable, helpful and caring. However a few weeks earlier I was trying to get surgical clearance and had some timing issues. But this had nothing to do with Dr. Hahm. She was great!

I waited over 2 hours in a freezing cold examination room. They should have let me know in advance and told me to go and rescheduled. Two hours is too long by far to keep a patient sequestered.
