My entire care team at Ashland Ortho has been amazing. I sustained a [ ] and between Dr. O and Jason, they put me back together. Chris (aka John) their MA always makes me smile and feel better every time I go in.

Jason and Dr. O listen and take the time needed with me. They are an extremely compassionate team and I am extremely grateful to have them as part of my Care Team.

March 27, 2024
Dr. O'Sullivan is a gem and the community is lucky to have this caliber of specialist. Technical prowess and authentically warm bedside manner.
March 27, 2024
Dr. O'Sullivan, and all of the PA's, and Courtney!
March 27, 2024
Dr O'Sullivan's whole team is excellent. I only feel that they are highly understaffed at answering the phone and that lack of staffing plus no automated answering/call-back system has caused me to wait on hold 15-20 minutes just to get my turn to speak with the scheduler. This feels like Asante doesn't believe my time matters as much as their bottom line. It's quite a contrast to the team of people serving there as well as takes my desire to go to Asante down a level.
March 25, 2024
Dr Osulivan is calm & very skillful. I sometimes feel guilty that he spends a lot of time with me because I’ve experienced a head trauma. He smiles a lot too. All the other people are kind & seem like they are glad to work there. Spotless environment too.
March 23, 2024
Adrienn [ ] was the best person for navigating insurance, prior approvals and urgent care appointments. None have matched her expertise. After she passed it took three months for me to get scheduled for an MRI. When Adrienn was alive it would’ve been a week or less.

My circunstances are different in that I was coming from a different area as a new patient.. I have been searching for a physician who would listen to my need to reonstruct a hip problem that has been on going for last five years and enduring extreme pain every day. The doctors in my area, Portland, Oregon, atempted to reattach a tendon that I pulled off left hip bone five plus year ago while vacationing with family in Hawaii after jumping from a parked helicopter. This operation was less than the desired results leaving me with a lot of pain and marginally functional left hip and leg. Consquently I have seen various doctors under my old insurane plan all who seem to feel I just need to manage pain for rest of my life. I am very encourage by Dr Osullivan and his abilities to do the reconstuction or his recommendation of a colleague in Portland area. I am waiting for the lacation for an MRI and Doctor follow up.
