Dr Toomey has done a Total Knee Replacement on both of my knees in the past 3-years (2nd knee was done 4-months ago). I have a very active lifestyle, and thanks to Dr. Toomey’s expertise, I am comfortably participating in a wide range of activities including mountain biking, hiking, surfing, sailing and wing-foiling without pain.
Dr Toomey and his Team take a personal interest in your success. They listen to you, discuss your options, and organize a plan to get you back operating in Top Gear.
I made a choice to travel over 3-hours to be in Dr. Toomey’s care because he earned my trust with the first knee replacement.
Your mobility is extremely important to your overall health and your Post-Op Therapy is up to you. As for the surgery, Dr. Toomey’s work stands out in a league of its own. You will not be disappointed in the results.

Minimized the true pain I am in questioning that the titanium implant causes discomfort. Went directly into a domineering point of view and made me feel less than human. Leaving me sad and uncomfortable. I get it that taking it out may be hard but he destroyed my optimism. I may get the MRI he requested but after the visit I’m just doubtful. He wanted to sell me a new leg it felt like with more implants that is not what I want. Google depicts removing this type of implant as routine.

He is actively involved in clinical research, has published numerous articles in peer-reviewed journals, and has given national and international lectures on joint replacement topics and advanced orthopedic techniques.
Dr. Toomey focuses his practice on minimally invasive hip and knee replacement surgery. This includes tissue sparing Direct Anterior approach for total hips and robotic-arm assisted techniques for total knee, partial knee, and direct anterior hip replacement surgery.
He performed the first robotic-assisted orthopedic knee replacement in Seattle in 2010 and has performed several hundreds since that time. Robotic-arm assisted surgery is the most precise joint replacement technology available today, and he is one of the most experienced robotic-arm assisted orthopedic surgeons in the greater Seattle and Puget Sound region, having performed over 500 partial knee, total knee and total hip replacements using this advanced technology. Dr. Toomey is committed to using the best techniques available for patients today while actively researching improved surgical options for patients in the future.
Dr. Toomey became interested in orthopedic surgery as he grew up watching his father, Dr. Hugh (Pete) Toomey, also a joint replacement specialist, interact with patients. Dr. Toomey is an avid soccer player, and played collegiately for the University of Notre Dame. His interests include reading, skiing, cycling, travelling and photography.
