“He actually takes the time to explain things to you on a level where a lot of physicians wouldn’t do.”

Dr Day is the best physician i have ever encountered in my life. He is very patient, caring and understanding. Dr Day wants to find the root cause of his parents medical issues. I am so thankful and blessed to have found him. Also his entire staff is Awesome.

Dr. Day is truly a diamond in the rough. It's not often to find a Doctor that genuinely cares and provide the very best treatment for his patients. Regardless of the workload & patients waiting to see him, he gives me his undivided attention and takes the time to really listen to my health concerns and overall well-being in every aspect. Additionally, his entire office staff are always kind as well as efficient and organized. I appreciate Dr. Day very much.

Dr. Day is refreshing as he is straight forward and doesn't mince words. Unlike most of my other healthcare experiences you know exactly what you're getting. They provide exactly what I'm looking for when I'm looking for any service. They make it extremely easy for prescription refills and referrals. I would recommend Dr. Day to anyone looking.
