I had an excellent experience with the provider. She asked questions, went back with my heart attack that I had five years ago, and I would recommend her to anyone. So I'm looking forward for my next visit. Thank you.

Dr. Welch spent a great deal of time listening to me and understanding my complex medical background. And explained things in terms that were easy to understand. Her approach was holistic and included lifestyle that I don't see often. She was decisive in the path forward and prompt to follow up with test results. Happy that I am under her care.

Each time I meet with her I feel like she views me as a whole person and truly understands where I am in my life and how some of my challenges may be affecting my health. She developed a treatment plan that helped me accomplish my health goals within that broader context, and it drastically improved my cholesterol, heart health and overall wellbeing.

Dr. Welch was awesome - as a new patient, I appreciate she took the time to first listen to me and understand me, balancing talking with me while also reviewing my medical history and charts. She then did an assessment and made a gameplan with me, including thoughtful discussion around steps I can take and what to do next. Absolutely great and I hope she will be at MGH a long time so she can be my cardiologist for many years to come!

Yes, Megan was very informative. She was very accommodating. She was never rushed. She took the time to listen to what I had to say. And between the two of us, we put things together and she figured out what was going on. And if it had not been her for taking the time and doing her thing, I would probably still be sick. So I thank her very much. Bye-bye.
