As a physician he was exactly what I had hoped for and needed. I felt he is a the top of his field. Having worked with numerous physicians I can tend to be more critical than most, with Dr. Xenon I felt he lived up to his reputation and everything I had learned about him before my visit. I am confident he will help me.

My 1st appointment with Dr. Zenos was personable, informative, he clearly explained what I could expect and showed me why! He was very thorough and professional with each visit that I had prior to my surgery and follow-up appointments. If I need further care I would defiantly contact Dr. Xenos and his staff for their care.

Between my husband and I, we have had 4 surgeries with Dr. XENOS. We think he is the best surgeon around. We have had great recoveries and outcomes. He is thorough, compassionate and skilled. Anyone who works near him in the hospital highly recommends him and says he is the one they would choose for surgery if they needed it. We are VERY pleased with him.

Dr Xenos did both knee replacements and a hip revision surgery on my husband. We recommend him highly and would never go to any other orthopedic Dr for anything. He is so smart and compassionate in his bedside manners and his staff is great as well. In addition all the nurses we have had at Sky ridge Hospital think he is wonderful.

Dr Xenos is a wonderful doctor. Excellent bedside manners. I've had both knees replaced and love my new knees. I highly recommend Dr Xenos and feel you cannot find a better or more compassionate person. If I have to wait to see him - it's not a problem because I know when I do see him he'll give me the time needed to express any concerns I may have. Remember - if you want the BEST sometimes you may have to wait.

I was a bit shocked to see so many patients in the waiting room as I arrived for my first appointment; however, I soon found that the "line" moved rather quickly. I was treated with courtesy by the receptionist, x-ray technician, and finally Dr. Xenos. He had been recommended to me by several friends, and I was not disappointed. He was thorough, answered my questions, and ordered blood work as well an MRI to ensure followup treatment proceeds in the best manner.

Dr. Xenos was a life saver in my situation related to my very much needed knee replacements. I had waited to long for the necessary procedures due to my reluctance to obtaining the needed surgery. Dr. Xenos and his staff are top notch in what they do and in their skill levels. His ability to have made me comfortable in the decision to have the knee replacement procedures were extremely encouraging.

My visit was great beside the wait time. My appt time was 10:30a.m. and was not called back until nearly 11:00. I did my follow-up x-rays and the was taken to a room where I then waited another 20 min before being seen. I would highly recommend Dr. Xenos as he is very professional and very informative which is one of the main reasons I choose to have him do my total hip replacement. I visited several other doctors and they simply said I needed a hip replacement without providing me with any additional information as to why I couldn't just have arthroscopic surgery to shave down the bone spurs or what the outcome would have been. The wait time at his office though could be a little more efficient, but other than that his staff is very professional and Dr. Xenos is as well.

He changed my life with my total knee joint replacement! I got it back. He is kind and actually cares about my quality of life and how to best achieve it. I am 3 years post op but had to have non related surgery a few months ago which set me back. He suggested strengthening exercises to get back to peak form as well as an Rx for PT. I am fortunate to have found a doctor like him.

Not satisfied with my visit, since it took over an hour to get my name called. Then they didn't even submit the request for MRI and its been 7 business days since my appointment. I called them today to follow up and they said they would call me back. Its 9pm and I didn't not recieve a follow up call regarding the request to see if they were going to submit the request for the MRI. I think I need to have my primary doctor find another office that will follow up in a timely manner.

Dr. Xenos did a total hip replacement for me one year ago. He was fantastic through the entire process. The hip replacement was a total success and at the one-year mark, I could not be more pleased. I am back to being active again with no pain. Dr. Xenos is the most caring physician I have ever been to. I highly recommend Dr. Xenos.

I called in the morning and was able to get a same day appointment. This was partailly luck and probably my referral with the results of an awful MRI had something to do with it. Yes, there was a wait but he was so apologetic that I knew it was because of the time he spent with each patient. He didn't rush and answered questions thoroughly. I feel very comfortable that I chose the right doctor for my total knee replacement! Cheri P.

They were extremely loaded with patients that day, though I was still taken care of, i.e. x-rays, etc. Several staff had jumped in to try to make the wait time less. They do have a nice array of hot drinks and things available, which was nice in the waiting room. Once in with different staff, I was cared for with diligence, good information, and kindness.

Highly recommended, Very personable. I was expecting to be told I need a knee replacement (turning 50 and blown ACL and torn meniscus) I like the sounds of the results of a knee replacement but don't like the sounds of the invasive surgery it takes. Dr. recommended that being healthy enough to get an ACL and repair meniscus and save total knee replacement for down the road if needed. Very happy with explanation of procedure and techniques used.

He is worth the wait. He performed surgery on my left knee and recently surgery on my husband's right knee. I was very concerned since my husband is almost 77 and his first knee surgery by a different dr. was not very good. The difference of day and night, we are extremely pleased; surgery on 12/20/2015 scar is like a small red line, he has been able to walk without any aids one month after his surgery. It has been six weeks and no longer requires therapy because he is able to use his leg with full range of motion.

Great Experience throughout the visit. Reception, Asst PA and Dr Xenos were truly professional. Dr. Xenos and his PA listened and approached my pain region very carefully and took the necessary time to explain everything. When their recommendations for improvement were offered and explained, my anxiety were reduced and my hopes for improvement gained tremendously. Thank you Dr Xenos and your PA.
