Patient Reviews

Patient

★★★★★

Dr. Morrissey had been my cardiologist for a number of years, until we moved to Florida. I always had the utmost confidence in him, both for his wealth of knowledge and his ability to convince his patients (me) to follow a healthy regimen. We were recently visiting D.C. from Florida (October 8, 2025), when I had a TIA. My husband quickly got me to the Georgetown Hospital Emergency Room. It was all pretty scary, with so many people scurrying around, questions being asked & IVs being put in. When I saw Dr. Morrissey enter the room I had an overwhelming feeling of relief. I just felt like "I'm going to be OK." It's only a two hour plane ride; and I won't lose track of him again.

The Cardiology staff were responsive and helped me to get an appointment and keep me informed. Dr. Richard Morrissey is a great physician who is friendly, competent, compassionate and concerned about my health. After a thorough exam, he reviewed patiently the results of all the tests and their implications. Then made clear recommendations as what are the steps I need to take to improve my health. Also gave guidance on preventive steps. Thanks to Dr. Morrissey and Medstar Georgetown University Hospital for putting me first!

I have been a patient of Dr. Morrissey for many years. Words can't express how happy I am to rely on his professional opinion and knowledge. He is attentive and makes sure to read my case file, including notes from other doctors, before each appointment. He is always on top of the latest medical research and shares it with his patients. What I like most is that he is an old school doctor who believes in preventative measures and cares about his patients. Thank you Dr. Morrissey!
