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.

This was the best and most thorough urgent care facility I have ever attended. I was MOST impressed with the physician and was so glad that I had him for a Dr along with his staff the day I chose to seek. Medical attention.

He listened, came up with answers, and the right prescription. Good Doctor.
May 26, 2022
Yes, hi. It's been a week since I last went and I'm waiting for my results. I was closed when I get it 3 days after and it's been a week now, every single time waiting for results. It always takes a week. That's the only issue. Alright, so other than that, everything is good. Thank you.
May 26, 2022
Was waiting for over 2 hours.
May 21, 2022
David Del Bello did a great job explaining everything thoroughly and in a way that was easy to understand.
May 18, 2022
Dr. Del Bello was professional, and very understanding. His compassion and suggestions have given me hope to cope with my medical situation.
April 22, 2022
Dr Del Bello seemed bothered by my health issue. I was in terrible pain, explaining I thought it was a kidney infection. My test was negative, which is great. I explained that I get kidney stones and asked for pain relief. He said that that office doesn't prescribe pain relief at that level. I felt judged by my appearance. I was there because something was painful. I didn't realize it was a fashion show. The staff was awesome.
April 21, 2022
The staff was friendly and the facility was very clean.
April 17, 2022
Dr. was very professional and took the time to check my injury and listened to my concerns.
April 15, 2022
Whittwood UC did a great job. Managed the office well and abided with all COVID precautions. Well run office!
April 15, 2022
The doctor was amazing. He called me on Sunday Easter to check and make sure that I was okay. And that I got my medicine and were taking it. I was very impressed with him. I would definitely go back to him again and the office staff was wonderful.
April 11, 2022
It was a great experience. I have had multiple visits to this office over the past 2 years and I have had repeated, superior experiences from all associates in this Urgent Care office. Cheers to this great staff. (PHI removed)
April 11, 2022
The wait time was extensive once I was in the room, waiting for the doctor to come see me.
April 11, 2022
Waited 2 hours only to be seeing for 2 minutes. It was a drive through experience.
April 10, 2022
I just felt that the provider was very curt and didn't really listen to me when I did try to explain, what I was feeling because I am very familiar with how my body feels when I do get this infection a lot. But you kind of disregarded my feelings and then just kind of made me feel that it wasn't important and then just went on with his plan without really considering what I have to go without it. So I was not really a fan of that.
April 08, 2022
I'm very Pleased with the service. I wouldn't change a thing. It's perfect As is.
April 03, 2022
I was impressed by how clean the lobby and treatment areas are and how professional the staff conducted themself. This was my first time at this site and will return when I need medical attention.
March 26, 2022
Excellent Dr. He said as courteous and very knowledgeable.
March 25, 2022
He was absolutely fantastic and a great doctor to see.
March 23, 2022
Was able to make an appointment by phone very easily and at a time that worked for me. Upon arriving and checking in, I was seen by the doctor just 20 minutes later, which was in fact 20 minutes earlier than my scheduled appointment. I was pleasantly surprised. Staff was very friendly and helpful. The doctor listened and answer all questions that I had. When he had a feeling that my blood pressure results were incorrect he had them done again. I will definitely be back next year!
March 20, 2022
Hi, this is (PHI removed). You guys can look up my file and the date that I have seen the doctor I am giving feedback on. This individual was very unprofessional. I felt disrespected, I was able to be comfortable and explain to a male what was going on with me at the time of my visit? I am very disappointed and it is very disrespectful on a woman's part from men. (INAUDIBLE) and the lack of professionalism he has
March 18, 2022
I had wax in my ears and I had to ask for an ear wash. I feel the doctor should have recommended the wash.
March 17, 2022
Great staff and rapid service..

February 28, 2022
It was clean and very welcoming. I have been coming here since I was a kid. I feel comfortable with the providers here and the office was amazing and very helpful. The doctor and nurses were very considerate and knowledgeable of my issues. Amazing job.
February 28, 2022
So professional and friendly. It was a great 1st time experience.
February 22, 2022
Thank you for the medical care.
February 21, 2022
I felt really sick by my throat, I still do. I wanted to get treated. The only thing he focused on was me having covid. Gave me a covid test, it was negative. But my chest was still hurting, I had a cough, felt like I couldn't breathe and again, he just focused on covid. He told me I should get a covid test that was more accurate. I asked him about my chest and he asked me, do you want antibiotics? Why is he asking me, he's the doctor. He should know what I need or I don't need. I went home and I'm still stick for the day, and I got no medicine or nothing for my chest, and I was very disappointed.
February 21, 2022
Very bad experience they made me wait 1 hour for the doctor to see me. Previously they didn't make me wait so long but this time it was lousy. Thanks.
February 21, 2022
Great doctor . He was very thorough and thoughtful of my pain and concerns
February 18, 2022
The doctor was extremely unprofessional. Wasn't really listening and wasn't taking what I went in for seriously. He barely explained the issue and contradicted himself the whole time. I would never recommend the doctors in the urgent care to no one. The office staff and nurses were amazing although the doctor sucked.
February 18, 2022
He was very attentive and showed concern. I was very pleased. Very kind and polite and respectful. He is a keeper.
February 11, 2022
the admission clerk and security were friendly. the staff that took me in to do vitals was not friendly, did not even pay attention when she called my name. i had vertigo and could barely walk. She did not even offer assistance or was considerate of my needs. She took my vitals and barely spoke to me. The office staff who gave me my medication and assisted me finishing up the appointment was very friendly and considerate of my condition.
February 04, 2022
He was great. Attentive, kind, humorous and all the while professional.

I have a very rare affliction involving possible viral (Epstein Barr Virus) infection in 2017 leading to on-going neurological/autoimmune issues. My arms were partially paralyzed for 18 months and now have extremely painful muscle and joint relapses lasting a week every 2-8 months. It ia a lifetime affliction as my other docs have concluded Dr. Del Bello spent close to an hour gathering my history and recognized it as a possible case the NIH in Baltimore MD may take on and got my case started by opening a first description of my affliction that will be sent to the NIH next week. He showed lots of interest in my issues being a rarity of any infectious disease doctor but also lots of empathy for me for suffering this. As a retired dentist, always reading everything and a knowledge of the medical sciences and terminology, Dr. Del Bello increasingly spoke to me in more of a professional mode than in lay person's terms, making it easier for him to quickly get to the important highlights, knowing I was understanding all he was discussing. We were both clear as to my next step to see my new neurologist and another rheumatologist as this current painful recurrences are not EBV-caused. EBV may have started this whole cascade of symptoms but now, it is an issue of an autoimmune triggered attack of the nerves of my neck, shoulders, arms, and back. Finally, after 5 years I may have an answer to this Parsonage-Turner Syndrome that was 1st diagnosed by [name removed] MD. one year after the start of this medical mystery. With the time spent by this doctor, wI was very impressed with his empathy, interest, and the honesty of his approach not to frighten me with the fact that this is a lifetime affliction, may have no cure, some chemotherapeutics approaches may cause other serious problems and like many autoimmune issues may get worse in the future. It was more of knowing what is happening, a relief in a way.

With so many people coming to for covid-related reasons, the process is still fairly fast-- and it's well-organized.
January 14, 2022
Yes, my experience was amazing, Dr. David Del Bello was phenomenal. He found the problem that was affecting me. I have spent all day in the emergency room on Tuesday, and he saw me Thursday, and he was able to figure out what was going on with me. He really listened. I actually wanted it to use him as my primary care physician. So I was looking into if that is even an option. When I called back today, to get my test results for covid. I'm covid-19 negative. But that has nothing to do with why I went in there. However, I was a little disappointed with the fact that I had a call in, for my results, and the staff sounded a little lost and confused when I went in there. I think the staff could be a little bit friendlier. That's just about it, but the doctor was phenomenal.
January 14, 2022
Long wait, but great care. Everyone was plesent and helpful.
January 14, 2022
Fortunate that Urgent Care is always there for me. I rarely shy from medical care, yet blessed to know of your Whittier location.
January 11, 2022

Knowledgeable, prompt, thorough.
December 27, 2021
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.
December 27, 2021
Doctor was great. Provided quick results and feedback. Vitals nurse wasn't very attentive, looking at cell phone when speaking.
December 27, 2021
Took to long to be seen due to being urgen
December 25, 2021
[name removed], the Medical Assistant or LVN that took my vitals was also very nice and respectful.
December 25, 2021
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.
December 22, 2021
I was very pleased with the way Dr. Del Bello has been treated me. I would recommend him to anybody. Thank you.
December 20, 2021
Very detailed patient and great place to receive healthcare!!

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.
November 17, 2021
First visit went smoothly and I am completely satisfied.
November 15, 2021
He took the time to reasure me and listen to my concerns. He gets high points for empathy.
November 08, 2021
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!
November 08, 2021
He was the first doctor that I've experienced there that didn't make me feel uncomfortable. So modern and friendly
October 18, 2021
Dr Del Bello is very thorough in his explanations. His staff [names removed] are great (very helpful and attentive).
October 15, 2021
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.
