There’s just so much to say! Dr. O. Jay & I go back many years when he worked in a different office. He was always so kind, so personable & easily made you feel like his only concern. Well he left & I moved & then lo & behold I neShow moreeded him bad! Found him, to my great relief & delight. I had a sizable MRSA infection on top of my hand & after my MD didn’t exactly know what this was, suggested Dermatologist. That’s when I found my ol’pal Dr. O. Jay. Wow he said without hesitation started working on it as soon as he sat down. It was pretty bad but he didn’t make it scary for me & just treated me and with lots of checking-in the 1st week. And lemme tell you… it was UGLY! It finally healed & there’s no lingering signs of anything there ever. Now I am on 6 month checks & it’s always nice to be seen by him & staff. He is same old “pal” - professional always but is just a real & authentic person and I feel safe and I feel 100% heard. Which says a lot as I have a significant speech impediment & he doesn’t give up on me. Wish he could be my doctor in every other scenario of my medical history, future. Thank you Dr. O. Jay - see you in 6!

O. Jay On, PA is a caring, experienced medical professional with a great sense of humor. He makes you feel at ease during your visit, and has the knowledge to diagnose and treat your dermatological needs. I have been going to him Show morefor close to 30 years, as well as taking my two teenage daughters to him when needed. When I was diagnosed with malignant melanoma twice O. Jay guided me through the surgical processes with compassion and follow-up. From my perspective I highly recommend O. Jay to be your first choice for dermatological care. He is the best!
