What Our Patients Are Saying

Josh D.
Excellent!
Brad H.
Doctors office... Friendly staff... Easy access... Have been trying to access their patient portal for years... Never successful... They appear to have all my current records, from all my medical care specialists... That makes me feel very secure... My being able to enroll in their portal would be a blessing... They had access to medical records that are unknown to Sparrow or McLaren.... Dating back to my Chattanooga DAZE

He has been my doctor since 1995 when he first started his business in much smaller office. I have 3 other family members that also go to him now that I referred them to Dr.Ross.

Staff makes you feel like you're no "just a number". They try to find convenient appointment times, I am very appreciated of my gastrologist and the PA that works with me. I most appreciate that they have helped with samples to see if they will work with me. That is wonderful.
Brooks J.
First, thank you to the staff, not just one or two, the entire faculty!!! Being helpful and out right solid people is at the core of this team, you can feel it upon the first interaction. I apparently had an issue where extreme Restless Leg Syndrome was induced upon waking up. I don't remember very much, it is my understanding that everyone was very understanding and interested in my best interest. I've been told about my out of character behavior and I apologize almost as much as I thank you. Your team has way more integrity and character than I could be out of character. Thanks again to everyone who helped. Truly a great group of human beings within these walls. You're the best!
Mary W.
Everyone was very caring and helpful. I was very nauseous from the medication that I had to take for the colonoscopy. Before my surgery I was vomiting and the staff kept asking me through the bathroom door if I was okay. They were very concerned. They gave me anti-nausea medication through my IV as soon as they got my IV in. Thank you for being so caring.
Luz F.
Dr. Ross was very assertive, direct, and clear in explaining everything. His professionalism and knowledge made me feel confident that I was receiving excellent care.

I was so worried about seeing a GI dr because I’ve been so tired of feeling unheard or dismissed. My appointment with Dr Ross left me feeling hopeful & very “seen”. I am truly grateful for how friendly, compassionate & considerate he was. The office staff was so nice as well. I’m so thankful there are still doctors out there that care & listen. Thank you to him & his staff!

Joen T.
The staff is really nice and friendly. They helped ease any anxiety I felt before, during, and after my procedure. Dr. Jones also made time to talk to me, before the procedure, about what to expect (which isn’t always the case with other doctors) so that was appreciated.

John C.
I've have had three, if I remember correctly, Colonoscopies and an endoscopy in the last 20 years with Dr. Yusuf. I found him to be very nice and the procedures went without a problem. In addition he prescribed Omeprazole when it was first coming out, before it could be found over the counter. My esophagus was pitted and damaged from GERD. His prescription was life changing for me. At last it didn't feel like I was burping lava all day long.
Krista Jo L.
Dr. Yusuf was very thorough and made me confident that he was checking my gastro system completely so I could relax about this area of my health.
Janet S.
The staff was very efficient, courteous and informative.
