Dr. Perezous is phenomenal! Not only did he conduct meniscus surgeries on both of my knees, but in this most recent situation conducted surgery on my clavicle! I am extremely active for a person in their late 40s and he has enabled me to keep the momentum going with the active outdoor activities I love of mountain biking, skiing, hiking/backpacking, and paddle boarding! He is very knowledgeable, he listens, is a phenomenal surgeon, and gives excellent guidance! I super impressed with Len Barry as well, who works with Dr. Perezous! The PT department with LOG has also helped me after all of my surgeries and am so thankful for their knowledge and working with me so that I could get back to what I love doing! Thank you so incredibly much, Dr. Perezous!

Dr. Perezous was very nice and friendly. He listened to my issue and explained clearly want he thought would help. I’m sure this was not his fault, but I did wait an hour past my appointment time.

When in with some pain in my right arm shoulder area, they did an x-ray and gave me a shot and I’m following up with an MRI to make sure I don’t have a damaged shoulder. They are very very thorough. They did exactly what I asked. I had been seen for this a few years ago and I asked for that shot in My bursa which gets inflamed and I have arthritis. They took care of everything. Excellent follow up.
