My experience with this office has been great for the past 6 months. Everyone is kind and always professional. From the front desk to the nurses and doctors I thank you for taking care of me.
The entire process from scheduling the colonoscopy, all the way up to learning the results of same, was smoothly handled. Even the preparation process! 🥴
But the peace of mind that comes from hearing that no polyps were found makes the entire process worthwhile. In addition, hearing Dr Otero say that my next exam will be in FIVE YEARS made me feel even better!

Great experience with Dr. Alvarez. He took his time and answered all of my questions. The staff was very friendly and professional too.
I would recommend Dr. Mallikarjun to anyone..I have seen her three time in the past month for an office visit and two procedures . Her and the staff are very compassionate, knowledgeable, and very professional..I love going to my visits with her.
I’ve been to Dr Otero before and he’s still the best. My interaction with him has always been about my well being and giving me the assurance I’m in the best care. Also, I want to give kudos to his receptionist Brittany Carter. She helped me tremendously in getting my medical procedures scheduled so quickly and effortless. She was the saving grace in calming my fears. Brittany’s professionalism, empathy, manners, efficiency, and attitude around service was greatly appreciated.
Dr Guerra has provided the very best in medical services over the last 25 plus years My mother and I have been going to him. He is genuinely concerned for his patients and give them everything he can to achieve the very best for them. Because they are so good there may be some waiting involved, but the wait is definitely worth it.
Since day one when I scheduled my rat visit with her,she has been awesome.
The staff is amazing and very helpful.
I will recommend her to any and everyone.
