Professional Overview

Shaun Callahan is an experienced personal injury attorney who has been representing the wrongfully injured for nearly a decade. He primarily focuses his legal practice on representing clients injured as a result of automobile accidents, dog bites, or negligence by property owners.

Shaun decided to become a personal injury attorney after his grandparents were seriously injured in a car accident when he was in his late teens. After witnessing first-hand how their injuries, hospital stays, insurance issues, and medical bills changed their lives forever, Shaun chose to dedicate his career to helping people in similar situations navigate the myriad challenges that can arise as they work toward recovery. The combination of his deeply rooted commitment to helping the wrongfully injured, his genuine compassion for his clients, and his determination to stand up for them against powerful insurance companies that seek to diminish the compensation they deserve is what makes Shaun such an exemplary attorney and effective advocate in the fight for justice.

In addition to serving clients across the Pacific Northwest, Shaun leads GLP Attorneys’ Legal Internship Program for the firm’s South Sound region. This program exists to provide meaningful work experiences for students in law school who are interested in careers in the personal injury field. Each year, GLP Attorneys is proud to employ up to 10 legal interns across Washington state.

Shaun is a proud “double Dawg”, having earned his Juris Doctorate in 2014 from the University of Washington School of Law after receiving his bachelor’s degree in political science from UW in 2011. While in law school, Shaun won the school-wide negotiation competition and worked as an intern for Intellectual Ventures and Avalara, Inc. After law school, he worked as an associate attorney at the Johanson Law Group in Edmonds before joining GLP Attorneys in 2016.

Shaun has been an Eagle Member of the Washington State Association for Justice since 2015. He has also been recognized as a Rising Star by Washington Super Lawyers since 2019 — an honor awarded to only the top 2.5% of attorneys in Washington state.

WhatShaun's Clientssay…

“I was in an accident in the middle of January 2021. These guys went to battle for me. They dealt with both insurance companies involved and I didn’t have to do much. They always emailed me back or called me back in timely fashion. They did everything they could to get me the biggest settlement they could for being out for 10 months. I appreciate not only Shaun, but Jill and the rest of the team that worked on my case. These are great people that want the best for you. I highly recommend them!!!”
- C.L.
“Four years ago my partner, Gerald Roby, was hit by a drunk driver while driving a small bus for work. He underwent several surgeries and was unable to resume his regular, active life. Shawn Callahan was right on top of everything, kept us informed and never quit going after the insurance company involved. It was a long process and Shaun, his paralegal Jill and this company never gave up! We finally settled for way more than we ever expected thanks to this amazing team. We are so thankful we had them to represent us. We highly recommend this company to anyone who wants to win. They will get it done!”
- M.G.
“At a time in my life when I experienced an injury that was out of my control – [as well as] the hardship of pain and not being able to work and the stress that comes with it for an uncertain future – retaining GLP attorneys immediately lifted the enormous burden of stress! [They had] outstanding professionalism, compassion, and were very thorough in the entire path of my medical process! I was confident and able to recognize that all entities involved in my case would have to show accountability. I appreciate very much every level of GLP Attorneys’ [process]; whether it was talking on the phone via messenger or in-person, all levels were very professional, courteous, and efficient.”
- J.S.
“We were involved in a car accident that was not our fault. We spoke with Shaun Callahan of GLP attorneys and we felt confident that he could help us. The at fault driver was under insured and therefore the claims fell under our insurance policy for underinsured motorists. The settlement took 2 1/2 years due to our insurance company not wanting to pay for the coverage that we have paid for for over 30 years. Shaun kept working hard, even through the COVID outbreak to pursue every avenue to settle our claim. He did successfully negotiate the settlement in a very favorable outcome.”
- C.C.
“Shaun was my injury lawyer. He was great! He not only was compassionate and responsive, he also was able to get me more $$ than I was actually allowed in WA. Because the accident happened in OR, Shaun knew of a rule that allowed me to attain substantially more $$. Wow, what a great lawyer. Even during Covid, Shaun and his team were responsive.” - T.C. “Shaun Callahan is wonderful! I have recommended your firm multiple times because of the great care he has provided in dealing with my case. He is now handling a case for my daughter as well. Shaun is great at what he does.”

God bless you Shaun, you are truly an outstanding and professional attorney.”
- R.B.
“I must say [Shaun] was the most professional, communicative and results oriented one I have come across. I have nothing but good things to say about him and my experience with GLP [Attorneys]. Building trust is paramount in my opinion between attorney and client, and after my first consultation with him I knew I made the right choice.”

I really appreciate Shaun Callahan setting my expectations early on as to what I should expect while going through the process of getting medical treatment, meeting requirements from the insurance company, and going through the arbitration process.
