Yes, Dr. Cullen was very knowledgeable. He found a solution that other doctors were not willing to find. So, and then he had a concern of another issue that he found treatment or had he signed up to get care for the other issue before surgery. So, very happy with so far everything that he's done.

I had great respect for Dr. Cullen after he repaired my left shoulder but I was very surprised with him and the way he handled my appointment. Walking in to the room he began chastising me for falling and I have to stop. I'm [redacted] and I guess I know falling is bad! I did fall about 2 years ago on the same shoulder Dr. Cullen fixed for me and wanted to know if that was the cause of why I'm having trouble again. He checked my strength and movement and another warning about falling and that was it. [redacted] Maybe that's his tactic to really getting someone's attention to heed his advice? I don't know but I did not care for it as you may be able to tell.

Dr. Cullen is great. He walked me through my MRIs and thoroughly explained the surgical plan to me. I do wish we discussed different types of surgical options, but I understand with my condition, there aren't many options. Dr. Cullen was amazing, and I can't wait for the surgery in a few days. He is friendly and provides a sense of professionalism with extreme knowledge of Orthopedics.

Yes, I saw Dr. Mark C. Cullen. Dr. Cullen is very personable. He's a fine surgeon. He explains himself very, very well. He made me feel at ease. He has a good sense of humor. Um, he doesn't seem to think very, you know, too highly of himself. Um, we got along very well and, um, I had no fear about the surgery. Uh, it was very, very well at ease and, um, I like Dr. Cullen very much. And if I needed another.

Overall he was a good provider. He listened to what I had to say. However he had zero sense of humor which is important to me in a provider. Someone with a sense of humor makes the experience more enjoyable.
