David Del Bello MD is an internal medicine doctor who specializes in infectious diseases, for which he completed a fellowship at Mount Sinai Hospital in New York City. During medical school, he took an infectious diseases elective course and after the first week, he knew that was the area he wanted to focus on to make a positive difference in people’s lives. He enjoys the thorough process of medicine, which is magnified in many ways in his subspecialty. He likes formulating thoughtful differential diagnoses, taking action based on his initial assessments and having results which confirm or challenge those assessments.

As an internist, Dr. Del Bello counsels his patients on their disease processes and actions they can take to treat or prevent it from happening again, so patients can have greater control over their health. While Dr. Del Bello consults on all manners of infectious diseases, he has extensive experience treating HIV, Hepatitis B and Hepatitis C. He also offers consultation for PrEP (Pre-Exposure Prophylaxis) in the prevention of HIV. He finds it gratifying that many infectious diseases can be treated, or better yet, outright cured.

Dr. Del Bello received a certificate of appreciation from the Central Louisiana Chapter of the American Red Cross and Fort Polk army base for humanitarian efforts undertaken in the wake of Hurricane Katrina in 2005. He was named Clinical Fellow of the Year for 2012-13 by the Mount Sinai Hospital Pediatric Residency Program. In 2014, he received the Travel Award at the HIV Liver Disease Meeting in Jackson Hole, Wyoming and the Young Investigator Award at the 2015 Conference on Retroviruses and Opportunistic Infections in Seattle, Washington.

Outside the clinic, Dr. Del Bello enjoys rollerblading and is a “massive” Star Wars fan.

The services were excellent that was provided by physician. Just the wait time was terrible. I was there for four hours. Maybe need to get some more doctors to be able to provide services.

When I left my appointment, we weren't sure if I had a break in my foot. He promised Radiology would call with results by 6:00 the same day. I never heard from anyone. I had to make 3 follow up calls and I did not hear anything for 24 hours after that.

I was sent to Dr Del Bello for long term skin mites that is most likely causing a block in my lymphatic system. All he cared about was that I already managed to get the rash to go away despite the constant crawling and them eating my hair. No rash=no treatment apparently. I showed him the pinpricks all over my chest that they're still leaving but again no rash so.... My extremely poor quality of life is so much more important than a rash. My need for treatment is still very evident. All he offered was an Hiv test which I don't need..... and when I told him that he kept trying to offer an Hiv test that I DONT NEED. Despite being sent to him by another doctor thinking the parasites could be causing the block in my lymphatic system- he decided it must be heart failure and that I should just go to a cardiologist. My heart is perfectly fine. The appointment with him was a complete waste of time and I would advise everyone to go elsewhere.

First visit went smoothly and I am completely satisfied.

He took the time to reasure me and listen to my concerns. He gets high points for empathy.

Urgent Care/Bright Medical staff were kind, considerate, helpful! This was my first experience at Urgent Care, the wait was not too long and saw doctor pretty quickly! Definitely would come back w/o reservation!

First of all, the first question answered I pressed 1 and I meant to press 4. Dr. Del Bello was amazing and so was the rest of the staff. He was very thorough, everybody was just very professional and efficient and kind. So I appreciate it more than I can say. I'm already starting to feel better even after a day. Thank you.

Hello, he looked the doctor looked at my my injury, but did not do an x-ray. And now it is, I had to go back again. And the, the infection got worse. His, his antibiotics weren't enough. He gave me a tetanus shot, which I appreciate it. But I think he should have done an x-ray. They didn't ask about the pain and I'm in a lot of pain. And so he should have counseled beyond the pain on how to handle the pain. And I've been through a lot of operations, knee replacement, back operation and the two most ones and it I, I understand pain, and this is very painful that I was going through. Okay. Thank you.
