Both my mother and myself have been patients of this practice for several years. Dr. Ilagan are kind and take the time to review things in detail. The staff from front office to the surgery scheduler and phone staff are always pleasant and accommodating. My mother won't stop praising the treatment she received from all the staff during her recent colonoscopy and keeps saying "A PLUS, A PLUS." I love that after all our colonoscopies you give us a folder with pictures detailing our results and instructions...and review them with us in detail!! WE LOVE YOU GUYS! GOD BLESS YOU ALL!

I had been battling stomach discomfort and changing bowel movements for months. Finalky, I threw in the towel and saw Dr. Ilagan. While our visit together was a bit rushed, Dr. Ilagan took my complaints to heart and ordered a ED(?) with scope and bioposy and colonoscopy with biopsies. I think it was more thsn I needed but was so wrong. Had 3 large polops , inflammation of stomach lining. More follow up apptmt will be set when bioposies come back. I am very pleased with the professional help Dr Ilagan pro ch ided. Dont follow my pattern: find out why you have digestive or bowel problems asap. Dont wait!! I highly recommend Dr. Ilagan.

Dr Ilagan was FANTASTIC. I went to see him for a second opinion after having a bad experience elsewhere, and he reassured me about everything. He was on time, sat down for the appointment, and treated my care like a priority. He asked questions to understand my condition, looked at all my lab work I brought in, and was able to actually answer questions for me. When I asked questions, he treated them like they were important and answered them, and he was knowledgeable. Not only did he diagnose me, he also noticed my old doctor had told me to take an ineffective medication for something else, so he managed to fix an entirely different problem too. After months of testing and bad experiences with other doctors, it was SUCH a relief to have a great doctor who cared and was knowledgeable. Thank you Dr. Ilagan.

I have been seeing Dr. Ilagan for five years and find him one of the best Gastro doctors that I have ever dealt with. His is very caring and thorough. My daughters also really love him as we all have a genetic issue that is very difficult to deal with. I would recommend him to anyone.
