I believe all surgeons must have two essential qualities: integrity and empathy. To me, integrity means treating each patient as if I were caring for my wife or children. Family is important to me.

Integrity means offering the highest quality of care available. I am an expert in arthroscopic (minimally invasive) shoulder surgery, but I will not recommend surgery unless all non-operative solutions have been explored and exhausted. The shoulder is an extremely fascinating joint with lots of moving parts. As such, injuries are common and often complex. Over the last few years, there have been dramatic improvements in the way we treat shoulder pathology. We are now able to perform most shoulder surgeries using arthroscopic techniques (small incisions) that are at least as good, if not better than, the open (larger incisions) procedures of the past.

Having trained with the world’s expert in minimally invasive shoulder surgery, the care and technical expertise you will receive is cutting-edge and based on the best available research for various shoulder ailments (rotator cuff tears, labral tears and instability, etc.). I am always actively looking for new ways to improve my surgical/nonsurgical treatment methods to help my patients regain their active lifestyle.

Lastly, surgeons are often not associated with empathy. This is unfortunate, because we are in the ideal position to support patients as they recover from difficult procedures. In my practice, your questions will be heard and answered promptly. By working together we can optimize the patient experience and maximize your health and well-being.
