He actually made me feel heard and understood! Years of doctors that didn’t care or take initiative to work with me! I am so glad i found him and he is going to work with me to help me get to a better health future.

Dr Mariorenzi, is so friendly and understanding.. He takes his time in listening to you and also in giving you his genuine advice.. He shares many other options, and leaves having surgery as a last resort...If you are looking for a knee surgeon or a second opinion, I would definitely recommend Dr Mariorenzi...
Blessed day!
