This is my first time being with an adult endocrinologist and I have nothing but good things to say. I felt very seen. As a hypo diabetic, it's difficult for people to kind of understand your disease and Dr. McDonnell was super, super helpful and gave me all the resources I needed to feel comfortable in my visit.

This doctor feels like a close relative to me. I can share anything with her and she hears every word and also, thoughtfully tunes into non- verbal emotions. Her expert knowledge and calm, reassurance is very comforting. She is a top- notch clinician. I hope, that if she is not already teaching med students and/ or residents that she will in the future, because anyone who shadows her can learn what it is to genuinely care for patients and families. I am so fortunate to be under her care. Thank you!

My wife and I were impressed with Dr. McDonnell from the moment she entered the exam room. More doctors could learn from her. Her demeanor throughout the entire visit was positive in terms of being open, asking questions, explaining the drugs I was taking and their affect. We even had some humorous exchanges which made me feel all the more confident and at ease.
