A friend of mine walked with a horrible painful hobble. After Dr. Parentis replaced both of her knees, she could skip around like a little girl. When I started to walk with a horrible painful hobble, I thought of my friend's new knees and called Dr. Parentis. After two total knee replacements, and I'm good as new. Dr. Parentis' manner is remarkable. Quiet, humble, personal, friendly, and one of the "Top Docs" in Buffalo. Pay him a compliment and he almost blushes. I recommend him to all.

Dr. Parentis was wonderful to myself and my wife at every office visit. He was pleasant and so helpful. Had my second foot surgery and it could not have gone better with an excellent outcome. Highly recommend him to anyone. Great staff. Very professional.

I could not be happier with Dr. Parentis and his entire staff at the WNY Orthopedic Surgery center. They have shown nothing but complete professionalism, and kindness during my recent knee surgery. Everyone from the secretaries, the PA's, nurses, and especially to the phenomenal Physical Therapy department. This kind of welcoming atmosphere is not always easy to find. Always available, always ready to answer any questions, and always very friendly! Will go again in the future!

I had both knees replaced in December 2015 and I couldn't be happier with the outcome. No more pain, grinding noise or buckling of the knees when using stars. Right from the start I had confidence in Dr. Parentis and his team. The office staff is professional and attentive. Followup has been consistent and exemplary. If ever I need additional orthopedic surgery this would be my first choice of surgeon.
in West Seneca, NY |
I avoided having knee for surgery for as long as I could, but when I wasn't able to do the things I enjoyed, I knew it was time. My experience with Dr. Parentis was excellent from start to finish and I was back to my activities sooner than I expected.
in Buffalo, NY |
From the very first phone call, the staff at WNY Knee and Orthopedic were very professional. Upon my first meeting with Dr. Parentis, he took the time to go over my x-ray and MRI. He explained everything in detail so I could make my decision easily. His follow-up calls after surgery and his staff's concern for me were overwhelming. The physical therapy department, which is located behind his main office, completed my rehab. I would highly recommend Dr. Parentis.

My experience with Dr. Parentis began with a hip fracture-----I had not met him or even heard his name before. Having said that, I feel very fortunate to have had treatment by him. From the first, he was humane, reassuring and available, beyond his obvious competence and preparation to deal with my issues. I require the care of more than one specialist, and Dr. Parentis compares most favorably by all parameters. He has my complete confidence, and appreciation for his kindness and sincerity.
in Buffalo, NY |
I have the greatest trust in Dr Parentis. He did my knee replacement and I am on the road to recovery. After my hip replacement, I will be going back to Dr. Parentis to have my other knee replaced. I would highly recommend and have recommended him to my family and friends. I have an appointment with Dr. Stube for my hip, and because of Dr. Parentis recommendation I have confidence that this will go as well as my knee.

Outstanding doctor and staff

March 2016 I fell and broke my femur. We knew that we needed a skilled doctor so my husband did some research and found Dr. Parentis. It was on the weekend but he made time for my emergency surgery. About a year later I am pleased with my results. When I fell I also tore my rotator cuff which he has recently repaired also. It has been a long year but throughout it I have felt very confident in the care of Dr. parentis and his staff. The physical therapist is connected with his office.

I have had a total knee replacement and shoulder surgery by Dr. Parentis. Also my husband had shoulder surgery by him. He took his time explaining everything to us about these procedures. He even showed us our X-rays and explained what he was going to do. He also has a physical therapy room and two wonderful physical therapists on site. They have all been great to us. I can not say enough about this doctor. I would recommend him highly.

In my line of work, unfortunately I've received several injuries to my knees and shoulders. I've found Dr. Parentis in particular, and his staff to be friendly, professional and skillful. They've always tried to accommodate my needs around my busy schedule as a Police Officer. I've had nothing but good results, through my several injuries and subsequent surgeries. I am still an active patient, and will remain so for the long haul. I have recommended Dr. Parentis to family and friends.
in Buffalo, NY |
Dr. Parentis has a wonderful bedside manner. He takes his time when providing explanations and answers questions regarding my care very thoroughly. Matt and the office staff are very kind and courteous. I would recommend Dr. Parentis to my family and friends without hesitation!

Totally satisfied with Dr. Parentis and his office staff. Had a knee replacement done by his associate, Dr. Stube a year ago. Dr Parentis was my follow-up Dr. He is professional and explains everthing fully. My rehab was done by the Pt. Dept. at his office. Everything ent smoothly. I recommend this practice for orthopedic problems.

Dr. Parentis did surgery on my left knee and am very happy with results! If I should need surgery on my right knee I would not hesitate to have Dr. Parentis operate on it! I would recommend Dr. Parentis to family & friends for sure!

I recently had a full knee replacement done by Dr. Parentis . He is very professional and has a excellant bed side manner. He explained the complete procedure in a laymans language at the pre-op office visit. My rehab was done by the physical therapist group that shares practice. Everything went great and I am well on my way toward full recovery.
in Kenmore, NY |
Dr. Parentis has now helped me twice. My recent shoulder surgery was done quickly and my care was perfect. I connected with the physical therapy department partnered with his office and they helped me tremendously. I followed all their directions and my shoulder is serving me well day-to-day and at the gym. Dr. Parentis has a confident approach that I really appreciated.
in Elma, NY |
Very punctual. Never rushes an appointment. Very patient explaining treatment, procedures and indication for recommended treatment.

I injured my Achilles tendon in late August, went to a "chain" type orthopedic and never felt comfortable with their prognosis. Dr. Parentis carefully took the time to explain my injury and options to repair... I've since had the surgery to repair and feel at ease that I am on the road to my recovery and active lifestyle, I would highly recommend him to anyone !
in Cheektowaga, NY |
Dr Parentis was a referal to me by a co-worker for a worker's comp case I have. From the moment I met him and his staff, I was impressed. He ran a few tests to find what was wrong with my shoulder. About a month later I was having a surgery on it. I could not be happier with the results! After the surgery, he and his Physical therapy crew continued to impress me with thier bedside manner and knowledge. I would recommend him and his staff in a heartbeat
in Buffalo, NY |
Services are always prompt & courteous. Sometimes I meet with Dr. Parentis & other times I meet with one of his PA's. Everyone is very professional and take time to answer any questions. He is happy to discuss how things are moving along, what I can expect and what options I have. I have recommended him to both family & friends.

I ruptured my Achilles in May 2015. Another Dr. recommended PT. I knew something was wrong and that I couldn't do PT. This led me to Dr. Parentis.. He recommended surgery, which I agreed to. 9 weeks after, I re-ruptured (my fault). Had a 2nd surgery with V-Y tendon lengthening. 5 weeks after that surgery I got an infection. After a long road of wound management and antibiotics, we did a 3rd surgery. I though I would never be the same, but I am back to biking, running, and a normal life.
in Tonawanda, NY |
Excellent, repaired my Patella tendon and I am as good as new .Highly recommended .Excellent follow up by Dr. Parentis and his staff.
in Buffalo, NY |
Terrible pressured me into doing unnecessary and additional surgery when there was no need too. I had the surgery was hospitalized with an infection on multiple rounds of antibiotics and never saw Dr Parentis for follow up visits only PA's. There was not one sink in the exam rooms for hand washing. I need additional extensive on an area of my foot that I didn?t have one problem with now in major chronic pain and need surgery and months of recuperation time.
in East Aurora, NY |
Dr. Parentis was very thorough with his explanation and what to expect pre and post surgery. His staff members are friendly, efficient, and knowledgeable. The facility is great and I look forward to PT sessions. At this point, I am seven weeks post ACL reconstruction surgery and couldn't give a better recommendation. If my other ACL goes, I'm coming back here.
