First impressions are so important when it comes to providers, and at my first appointment Dr. Diaz blew me away with his kind, thoughtful, empathetic, thorough, and often humorous approach.
He really listened to me unpack everything about my personal and family medical history, and my current concerns, and I never once felt that he was trying to rush me along to get to his next patient. He even personally wrote reminders to me with my lab results to keep me on track with my goals. I never had a PCP like him and I hope to stick with him for a long time to come.

Great doctor. Affable and gregarious. Was my first time visit, I was so relaxed it was questionable whether I needed blood pressure meds at this point which was the main reason I went in in the first place.

I had been putting off getting a pcp for literally years- finally - I decided to take control of my heath and wellness. I found Dr. Diaz-Lacayo on zocdoc and I was able to very easily book a time that worked for me- online- which is important to me. Wendy, the nurse that saw me before seeing the Dr was so nice and kind- Dr. Diaz-Lacayo was SO wonderful, kind, funny and just an awesome doctor. I am so grateful I found him!
February 13, 2019Kaitlin G.Verified patient
Dr. Diaz-Lacayo is an outstanding doctor who clearly cares for his patients (my 91-year old Mom and me, 65 yrs. old) and takes the time to listen, offer options, educate us about conditions and treatments, and streamline the process. He has a great sense of humor, is a recognized expert in primary care and how to make patients feel comfortable. We feel very blessed to have found such a brilliant and kind doctor!

Dr. Diaz is a caring and well educated professional. He values treating the whole patient rather than just the ailment. He is a breath of fresh air in the ever-increasing corporate environment healthcare is becoming. His staff is friendly and accomodating, the office is nice and easy to get to. I love everything about my visit with him!
