Ahl Jeffrey Caseja MD is an endocrinologist specializing in diabetes, thyroid, adrenal gland, metabolism, and osteoporosis. After his residency in internal medicine at the UNLV School of Medicine, he continued his training in endocrinology at the Sunrise Health MountainView Hospital in Las Vegas. 

Dr. Caseja chose endocrinology because it requires a comprehensive understanding of physiology and biochemistry, combined with objective interpretation of labs with clinical symptoms. Growing up, he had witnessed family members suffer with diabetes which motivated him to go into this field. Endocrinology is rapidly evolving and he has an opportunity to make a positive impact on the lives of patients while building life-long relationships. Dr. Caseja always tries to ensure that his patients’ questions and concerns are addressed during their visits.

Dr. Caseja served as chief resident at UNLV and has received the UNLV Residency Teaching Award, the Endocrine Society Early Career Forum Award and the American College of Physicians Young Achiever Award. In his personal time, Dr. Caseja enjoys traveling.

Excellent Doctor! Always helpful and gives me whole picture on my results. Most especially getting info when computers were going up and down. Has helped to improve my health!! Nursing staff great too! (name removed), RN always helpful with questions from portal!!! Thank you!

Very cut and dry. Was not very personable. Was kinda vague with his advice leaving it up to me to make some decisions. I asked the Dr to please note the info that he explained to me on the portal and he replied, angrily-you can't tell me what to write on the portal. I told him I just wanted the other Doctors to see what he explained to me as 3 other doctors are involved with the outcome of this appointment and the possible med side affects that were prescribed to me. they all wanted me to see this Dr for his opinion. So it's only proper that the other 3 doctors are aware of what he explained to me.

Dr. has provided excellent information about my condition. I got answers to questions about lab results and my guidelines that would inform me treatment as necessary. I was able to update personal changes of meds, family trans portion etc. that might be a problem and we jointly planned ahead.

I was taken in to the examination room within 5 minutes of my arrival. Saw the doctor almost immediately. Everyone was gracious and smiling. It was a very uplifting expierence and the doctor gave me good news from my biopsy. It was a wonderful appointment.
January 15, 2026
Everything went very well with this doctor. He's a very good doctor. He knows what he's doing, what he recommends, and he knows how to listen to the patient when they're talking to him. I'm very happy with him, and that's why I make my appointments with him on time. Thank you.

I feel very comfortable with Dr. Caseja.

On behalf of myself, Dr. Carseja is an excellent endocrinologist. He has helped regulate my diabetes and my other health concerns. He's been on top of everything that I need. He's an extremely, extremely smart doctor and knows what he's talking about. I recommend him to anybody, my family members or friends. If it wasn't for Dr. Carseja, I wouldn't know where I would be with my health. He's like I said, he's extremely knowledgeable and very, very good at communication skills and good bedside manners. And his crew there at the clinic, they're all team players. So I would highly recommend this office and Dr. Carseja and his whole crew there for being extremely caring and understand all my medical needs. Again, thank you very much for having people like Dr. Carseja take care of people's health like mine and other people that go and visit him too.

PIH Team was very helpful overall Department
December 19, 2025
I liked how the nurses across the hall treated me. The people who prepare you are very kind, super kind. I just wish the doctor had a slightly gentler way of making comments. That's all. Thank you. Thank you.

At this time my doctor has helped me lose weight and start to reduce my insulin level. He is a quality doctor who cares about his patients.
December 12, 2025
At my recent visit, I actually walked into the wrong office site. I called the office and said I would be about 15 minutes late. I was so gratified to be able to be seen despite my tardiness. All of the staff were very kind, from the reception to the doctor and the nurses.

October 14, 2025
very good
October 14, 2025
First of all, the staff is excellent-very attentive-and the doctor or student who saw me before the main doctor was very kind, listened to me, and explained things very well. In contrast, the doctor seemed to be in a hurry to leave. When I asked him to repeat things, he said, "You have the portal; it will be written there." I told him, "I'm sorry, it's just a lot of information," and I really meant it because all of this is new to me. Also, every time he asked me questions about my primary doctor and the surgeon, he would say, "What kind of doctor is that?"-and that didn't make me feel good. In a prof way he shouldn't talk about other Doctors

I was due to get my 2nd Prolia injection and they did not have the injection at the time of my appointment. This is not the first time this has happened and is extremely unprofessional. I have a 30 minute commute to the office so a phone call to reschedule would have been nice.
