After leaving the orthopedic practice in 2005, Dr. Lewis continues to practice in Renton focusing on conservative and surgical management of foot and ankle problems.

“ We pride ourselves in punctuality, transparency, and innovation. Most importantly we want to provide our patients with pain relief as quick as possible. We have created a family atmosphere where all patients know what they can expect in relation to their insurance at each visit. We preauthorize all potential services and share that information with our patients in advance of those services. We have the most modern equipment and innovations to treat our patients. We have orthotic technology developed by Hewlett Packard called Fit Station. We have the ability to utilize 3D printing technology. It is revolutionizing the custom perscription orthotic space with its precision. We have dedicated orthotic labs in each of our offices in which we can perform complete gait analysis and orthotic evaluation. We are also very excited to offer Mutli-Lock-System Robotic Laser treatments (MLS) for both acute and chronic inflammatory condtions.”-Dr. Lewis

Outside of work, I love spending time with my family. Petrina and I have three children: Zach 20, Nick 18, Alexa 15. Zach is a student-athlete and collegiate quarterback, Nick attends UCLA studying economics and chemistry, and Alexa is a high school sophomore who loves to work out at Orange Theory. I am an entrepreneur at heart and I love serving as a mentor to others who are passionate in their pursuits of their personal goals. I also can be frequently found cooking meat on my Traeger Wood Pellet Smoker. I look forward to the opportunity to getting to know you and help you lead a pain free, healthy , and active life!
