“I consider communication with my patients as my strongest asset and pride myself on ensuring that you understand your health condition and treatment options well at the conclusion of your office visit. It is important to me that we discuss all treatment options for your orthopedic problem, including non-surgical approaches such as physical therapy, medications, injections and activity modification. Surgical care is recommended only when clearly indicated, and often after a course of non-surgical measures have been tried. I do not utilize physician assistants or extenders in my practice. You will be seen and evaluated by me personally at each office visit. With my extensive experience and training, I will partner with you, build a strong doctor-patient relationship, and always do my best to help you build a stronger you,” said Dr. Stull.

Terrible doctor. He replaced my left hip. It popped out of joint, very painful, and had to be put back into place. This happened 2 more times! Lots of pain, multiple ambulance rides and lots of $$$. I had to have this hip replaced a second time, this time with a sincere doctor who actually cared. I’ve been fine since but my leg is now extra long since each surgery extended the length. My new doctor could not believe the angle Dr. Stull set my hip at…it was way off to the side and it was inevitable that it would fail. Dr. Stull has a huge ego problem with his little lacrosse stick and helmet and Kroks. I thought he was cocky and his work was poor. I would not recommend him to anyone.

Dr Stull was a referral from my primary physician. I am glad I went with him, for my hip replacement. The surgery went smooth, Physical therapy was surprised how fast my recovery went. My surgery was February 18th and I returned to work April 11th. I am very pleased through the whole experience. Will definitely be using him again on the other side.

I love Dr. Stull and his Nurse. He did a fantastic job on my knee. I am thankful for his skill and the kindness of his team. You cannot go wrong with this doctor. He is super funny too. The best part was how comfortable he made me feel through the whole process.

From the day Dr. Stull was recommended to me… he was informative, friendly and made me feel at ease with all my questions. Before my knee replacement… not only did I think he was a good doctor, but many of the staff at the surgery center said he was very good after I mentioned he was my doctor.I am now on the road to a good recoveryand looking forward to many actuaries this summer.

Dr. Stull is a no nonsense, positive, straight shooter. From my consultation to surgery and now to recovery has gone as planned. If you have been putting off hip replacement surgery like I had stop and trust in this guy and staff.I would be remiss if I did not point out his nurse Katie who is a life line when you have questions.I’m so glad I found Dr. Stull to guide me through this life changing decision.

Dr. Stull’s Testimonials

“Thank you Dr. Stull for fixing my knee! I cannot say enough about the care I received from you, your team and your PT’s. After shredding my ACL skiing and the subsequent repair surgery in February 2014, it seemed highly unlikely I would make it to the start line of the Ironman World Championship in Kona, Hawaii a mere 8 months later. But with your care and guidance I did start and FINISH Kona, placing 16th in my age group. Needless to say, I am thrilled with the results – of my knee surgery and my Kona finish!”

Thank you!

Dr. Stull is absolutely amazing, in fact I personally refer to him as the “Knee Magician”! I didn’t even have to take a single pain killer or Ibuprofen post op!!! I had a previous knee surgery in FL for the same injury and it took over a year to even be able to walk down the stairs easily… I’m 6 weeks post op with Dr. Stull and I feel great already. I’m so motivated at PT to continue to strengthen my knee and leg to get back to playing with my two rambunctious boys.

Thank you, Dr. Stull!!!

Exceptional surgeon. Have had excellent results following total knee replacement, then later, total hip replacement. Doctor Stull is a skilled doctor, and is also a very pleasant person. I have always been impressed by the kind and caring way he has treated me. As a professional pilot, I needed a good doctor, and I found the best. If I ever have any orthopedic problems in the future, I will see Doctor Stull, and no one else. He has earned my respect. Highly, highly recommended.

I never ever had surgery in my life !! Until Dr. Stull Worked On My Left Shoulder. I Was Scared BIG TIME !!. I’m 55 years old And Never had any type of invasive work done of any kind. Did I mention I was terrified ? Well…… All that worry for nothing. Dr Stull assured me I would be OK. And I Was ! He Is My Favorite Doctor of all time. My Shoulder feels great and so do I. Dr. Stull Is A Cool Guy.

Courteous, thorough, professional team and staff. From the initial diagnosis and recommended corrective action I received the utmost attention and care when I needed it leading up to and post surgery. Dr. Stull’s assistant Katie is a great patient resource that I called upon frequently. Always answered concerns in a timely manner. This is a World Class Professional Team of Surgeons, technicians, and assistants . You’d be hard pressed to find something superior! Looking forward to next surgery.

For two years I have been dealing with constant knee pain. I could no longer walk long distances, ski or play hockey due to the pain. In addition, sleeping was becoming difficult. About 6 months ago, I went to see Dr. Stull for this. He was able to identify the problem via an MRI, scheduled a quick scope surgery, and three weeks later, I was skiing again. This has truly changed my life. This guys is the real deal.

Dr. Stull is wonderful! It seems as though he has become our family doctor. He really knows orthopedics. We have had the best experiences from office visits, surgery and recovery for ACL (my husband), Rotator cuff (my son), Total hip replacement (my grandfather) and recently Total knee replacement (my mother). I highly recommend him and his staff especially Katie, almost everyday!

Kari C | Aurora, CO

Excellent bedside manner: provided information, requested inquiries and made sure all were addressed, listened, respectful, efficient, personable, spoke to both the patient and the spouse, explained the procedure prior to its performance, provided educational materials via staff. Allayed concerns. picture of normal, bad, and “new” knees most helpful. Surgery scheduled September. HIGHLY recommend !

Paula / Molly | Aurora, CO

Dr. Stull is remarkably patient, kind, & brilliant. I came to see Dr. Stull for a second opinion after a well-known Denver Metro orthopedic surgeon came up short in evaluating and treating a severe injury to my Left knee with associated soft tissue injuries. Dr. Stull spent a great deal of time reviewing my medical history and chief complaints; I was impressed with His knowledge and patient-centered approach to medical eval and tx. I am six wks post op ACL reconstruction and better than ever.

Kim B. | Denver, CO

Dr. Stull is an exceptional orthopedic doctor who treated me in repairing my torn meniscus. I had very minimal pain after surgery and would highly recommend him. Not only was he very professional, experienced and respectful, he was also very personable and took time to listen to me.
