"I have known Dr. Khalfayan for 15+ years as both a colleague with the Seattle Seahawks and as a patient.  I am a current NFL strength and conditioning coach and had a similar role with the Seattle Seahawks. Over the years I have had the opportunity to work with numerous players that Dr. Khalfayan has operated on or treated.  My experience with these players has been very positive.  Athletes trust Dr. Khalfayan and so do I - Dr. Khalfayan operated on my shoulder and both of my knees.   He got me back to exercising and doing my job with our athletes very quickly.  I am very grateful to Dr. Khalfayan for the great job he did for me and for our football players.  Not only is he one of the best doctors in Seattle, he's one of the best in the NFL."
