Dr O is the best doctor I've ever
had! I've been going to him for so long. I'm 82 and I have a few medical issues related to my golden years. I get my regular check ups, Dr O makes sure of that and takes all the time needed to explain everything. God bless you always Dr O. Thanks for taking care of me and my husband. You're our guardian angel!

Been a patient for many years - Dr. Ontanillas is the best! Takes his time, explains lab results etc and discusses your specific medical needs. Highly recommend this doctor!

My 92 y.o. mother and I have been going to Dr. O. for over 20 years. We have nothing but good to say about him. He takes whatever time is necessary to make sure we are taken care of. My moms in stage 4 dementia and he is so helpful and kind to us both. His caring for her is the best I've ever seen. We adore him. Wouldn't go to anyone else. Hope we never have too. Nothing but admiration for Dr. O.

Dr. Majonel Ontanillas is an amazing doctor that really cares. He’s very kind, patient and polite; and he’s very knowledgeable in his field as a medical doctor. Another thing I admire about Dr. Ontanillas is that “He Really Listens,” especially to all of my concerns and sends me to the right specialist if needed. I’m well pleased to have Dr. Ontanillas as my primary care physician.

I decided today this doctor has no time for me. I felt rushed and like he didn't want to hear what I had to say.
I went straight to the front desk and asked for another doctor.
