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.
