General Information

I am a board certified sports medicine physician specializing in sports and musculoskeletal injuries and prevention. I treat all problems relating to sports and exercise for elite athletes to weekend warriors to anyone interested in starting a new exercise routine. I am one of the first physicians in the US to receive certification by ARDMS in musculoskeletal sonography. I use musculoskeletal ultrasound to provide precise, diagnostic, minimally invasive, office based treatments for musculoskeletal and neurological injuries. I can look inside injuries to see the damage and perform office based regenerative treatments, like blood and platelet rich plasma injections and Tenex Tenotomy. I also provide evaluation and treatment for sports concussions in all ages, sports team event coverage, and electrodiagnostics for neurological injuries. I am the co-founder and co-director of the sports concussion clinic at Swedish. I am also one of the core faculty and the primary musculoskeletal ultrasonography instructor for the ACGME Sports Fellowship at Swedish. I have provided sports medicine for the Seattle Reign, AVP Volleyball, Lacrosse, Seattle University, Puget Sound Gunners Soccer, Sacramento Mountain Lions (a United Football Team), USA Boxing, UFC Mixed Martial Arts, sports teams at the high school and collegiate levels, and Issaquah Gunners Soccer Club.

I recently wrote a short post for the Issaquah Soccer Club on the topic of sports & energy drinks.

Atlas of Ultrasound Guided Musculoskeletal Injections

March 28, 2014
The most comprehensive atlas of ultrasound guided musculoskeletal injections is now available! I contributed a chapter to the hip section. This book is considerably more comprehensive than another book just published with the same name and has contributions from many all-star sports medicine physicians. Click here to check it out.

Sports Concussion Clinic and Community Education

August 05, 2013

This past Wednesday, July 31, Dr. Renee Low and I provided a class on sports concussion education to Issaquah youth athletes, their parents, soccer club coaches and trainers.  We hosted about 47 attendees and discussed signs and symptoms of a concussion, risk factors and prevention, when to seek medical attention, and baseline testing. (Click here for a PDF that explains concussions and some of the symptoms.)

We also discussed Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) now being offered at Swedish.  Swedish Spine, Sports, and Musculoskeletal Medicine is now offering a sports concussion clinic for youth and adult athletes.  We provide assessment of concussion severity, physical evaluation, ongoing monitoring, neuropsychological evaluation, education, return to play, and academic support.

Supporting the March for Babies

Dr. Packia Raj and I helped with the March of Dimes Walk (March for Babies) on Saturday, May 4th at the Seattle Center. The March for Babies is the longest-running and most widely recognized walking event in the nation with 2013 marking its 75th anniversary. This fundraiser incorporated thousands of volunteers participating in a fun-filled day of walking to raise money in support of lifesaving research and programs to make sure every baby gets a chance for a healthy start in life...

Why you should take sports concussions seriously

February 05, 2013

Concussions are serious injuries that should be treated by healthcare providers who are experienced with their management. Sports Medicine physicians diagnose and treat concussions with the goal of promoting a healthy recovery and returning athletes to sports and kids to school. Additionally, we work with parents, athletes, coaches, and other providers to identify the signs and symptoms of a concussion and help to proactively manage the effects.

What is a concussion?

A concussion, also referred to as a mild traumatic brain injury, is an injury to the brain caused by a blow to the head or from a whiplash effect due to a hit to the body. Concussions change the way the brain works and how a person thinks, acts, and feels. Most people do not lose consciousness. Even a "ding" or "bell ringer" can be serious.

What are the symptoms of a concussion?

Symptoms fall into four categories: physical, cognitive or th...

Patient Ratings and Comments

The Patient Rating score is based on responses given during the CAHPS Patient Experience Survey. Responses are measured on a 10-point scale, with 10 being the best score. These scores are then translated to a 5-point scale in order to display results in a 5-star rating. Comments are also gathered from the same survey and displayed in their entirety with the exception of any language that may be considered slander, libel or contain private health information, which will be removed prior to publishing the comments.

I wish all doctors could be as caring , understanding, and effective as Dr. Colio and the people in his office.

Dr. Colio spent a lot of time with me describing various options for treatment. He gave me literature on each of the options and explained next steps.

Dr Colio takes time to address all concerns, shares results of tests & diagnosis, also makes sure you have supplemental tools to further help you recover.

I would have had a VERY good experience, but didn't feel I had an opportunity to ask questions about what he told me - somewhat rushed.

already have referred atleast 5 people

Dr. Culio was great at diagnosing my injury with the first visit. He listened and asked questions regarding my pain and the injection he gave me at his office on my first visit brought quick relief. He gave me a prescription for PT and on my follow-up visit I was experiencing a lot less pain. Now I'm feeling like I'm going to be able to run again. Thank You Dr. Culio.

Loved him. He was very thorough & kind.

I have already recommended this provider [...]

Dr. Colio was friendly, helpful, good-humored, and communicated what I needed and/or wanted to know. I have no complaints and would go to him again.

Felt very rushed by everyone. Vague after care instructions, incompetent staff attending phone. Very hurried along by all doctors involved. [...]

Dr Colio and his medical assistant [...] are such a great team!

[...] the nurse for the doctor I think her name is, was very nice and helpful and told jokes to put me at ease

This was the worst experience I have ever had with a physician. [...]
