Her office staff is friendly and they are always able to accommodate a quick appointment and appreciate the longer appointment times. Recommend to anyone who is need of the best medical treatment!

When I had exhausted my change of Dr.s , who never listened and find my problem I went to Dr. Isselbacher , she listened to me for an hour or more and before she could make any changes to help me , I ended up In ICU on life support, she talked with all dr.s who were baffled with what was wrong with me, and because she listened to me , told them what to look for . Thank you Dr. Isselbacher , I’m alive and well 16 years later. Thanks to you and Brigham and Women’s Dr’s who listened to you and saved me from being sepsis , punctured bowel and bio duct to liver clamped shut after being damaged. I’d have to give her 10 stars out of 1-5.

Great Experience, I wish all the doctors and clinics work the way these guys do. Always responsive and willing to help. They got me in with a top-notch specialist same week!

Unprofessional, unsympathetic, does not seem to enjoy the profession of helping people. Save your money.

Dr. Kate has been my doctor for about 6 years - I've found her to be one of the best doctors I've ever encountered. She cares deeply about her patients and is very knowledgable. She goes above and beyond by reading about my medical issues to know the latest. I feel lucky to have her as my doctor!

Interesting comment by previous reviewer about dr being more concerned about her looks. Than accurate diagnosis. I see that point. My concern is that dr seems more scientific in approach than methodical, not as practical as a dr with her years of experience should be. Not sure good diagnostician.

She actually had her dog in the office at both my visits- talk about unsanitary!!! The whole environment seemed unprofessional and the Doctor seemed to care more about how she looked than about my medical concerns. Stay away and save your money!!
