Dr Louie was very thourough with his process of assessing my case by referencing records from my primary and specialist physicians and questions he'd asked. He also answered questions I had respectfully and completely to assure I understood.

Dr Louie was personable, thorough, and patient. He put me at ease immediately. He is highly intelligent, explained things medically and in plain English. I would definitely recommend him.

Dr. Grant Louie was thorough, knowledgeable, and instilled confidence in his judgment. He listened closely and took my complaints seriously as to what had been happening to me, bone issue, after bone issue, for the last year. Dr. Louie was the first medical provider of many I had gone to for help that made me feel heard, and that he was there for me, present, to try and figure out what was going on. He was the first medical provider to order very specific tests to rule in or out certain findings and recommend a course of treatment based on the testing results. I am so relieved and thankful to have found Dr. Louie to support me with his kindness and expertise in trying to regain my health. I cannot express how much it means to me to be listened to sincerely and thoughtfully and have Dr. Louie offer sound advice, and a plan, based on diagnostic evidence. Dr. Louie is my Go-To guy going forward. He is everything you would want in a medical provider when your health is seriously compromised, and you are in need of kind, reliable guidance.

Dr.Louie is the BEST Rheumatologist I have encountered here in Maryland since moving from Orlando. He is thorough, knowledgeable, kind,attentive and doesn't treat you like a number. He answers questions without frustration & gave me piece of mind in proper diagnosis. For years since moving here I felt unheard and not properly diagnosed. The few rheumatologist I did see treated me as if my health issues were completely over dramatized and Dr. LOUIE SAVED me with proper diagnosis. Can't say enough good about him.

Dr Louie was very professional and explained things to me in a way I could understand how I may have gotten my Arthritis. Very kind!

Dr Louie and his PA, Eden, were both amazing. Everyone in the office were very friendly and knowledgeable. They were able to take the x-rays on site that were needed to get me my diagnosis quickly. Although I was giving a lot of information, everything was explained in a language that I could understand. I drove 45 minutes to see Dr Louie, and it wasn't time wasted. I could find a doctor closer to my house, but I don't think I could find a better fit for me.

The Doctor and his Assistant provided perfect help and assistance and answered all my questions in detail. I am very grateful.

Dr. Louie is one of the most conscientious physicians I have ever met, and by far the best rheumatologist I have had. He worked at both NIH and Johns Hopkins in the past, and his level of knowledge is quite apparent. In addition, he has a kind personality and takes time to explain everything and answer your questions. I would recommend him to everyone in need of a rheumatologist.
