My medical appointment was great and I will miss Dr. Hahm tremendously. She is wonderful! My only complaint is with the parking at the hospital campus. It is terrible and takes a lot of time to find a space! Something needs to be done!

Dr. Hahm is one of the best, most thorough doctors that I have ever been to. She explains everything, and if she feels like you don't understand, she'll explain it in another way. She's very thorough, and I just feel completely cared for in her hands. So that's my feeling about seeing Dr. Hahm , and her staff are wonderful, too. So that's all. Thank you.

Dr. Hahm is an exceptionally thorough doctor, very caring, listens to everything you have to say, makes suggestions and treats you as an individual, like she sees you. She doesn't give you the protocol treatment. And hospital is going to lose an exceptional individual when she retires. I just wanted to say that. Thank you.

I did have an excessive wait time, over 1 hour. When I arrived for a 1:30 appointment an announcement was made in the waiting room that patients with 12:15-12:30 were just now being seen. I realize in this practice unforseen issues can cause delays. Perhaps a text message to patients scheduled later could inform them of the delay and they could arrive later for their appointments.

I will sincerely miss Dr. Hahm who is retiring next month. She is the absolute best!
