They were personable, and everyone spent a lot of time with me trying to figure out what my issues were and how we could treat them. I am thankful for that uplifting experience which made me leave hopeful for results. Thank you!”

“One of the best Doctors for Rheumatology . He is extremely knowledgeable and considerate. All questions are answered. I very highly recommend him. I am glad that we found him and his staff.”

R. Willis in Port St. Lucie, FL – Nov 21, 2018
“Dr. Khan is so compassionate and caring. She really listens and takes the time to make a complete and informed diagnosis. I like how she smiles and is genuinely concerned for your well being. She thought about alternate diagnoses that other rheumatologists have not. I would recommend her to friends and family.”

Cassie, January 26, 2019

“Dr Khan is one of the best doctors I have been to since I’ve been living in Florida. She is kind patient and unbelievably intelligent. She knows her stuff and is very willing to share that info with you. You never feel rushed and she is always willing to go the extra mile to assure you understand everything and have access to anything that will help you. I absolutely love Dr Khan and would highly recommend it her to anyone!!!”

Patricia C. – Oct 20, 2018

“Overall great experience. I found Dr. Khan very easy to talk to and willing to discuss my concerns, not discount them. We focused on ruling out things that had my attention, because I had a parent that suffered for many years with Rheumatoid Arthritis and it is a very real concern for me.”

Jenny G. in Palm Beach Gardens, FL – Oct 02, 2018

“So kind and patient. So knowledgeable. Listens. Great office! Top notch!”
