“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 Shawn, 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.


“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.


“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.


“Mr. Shaun Callahan was very helpful, responsive and always listened to what I think.” -M.T,


“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.” -Anonymous


“Dear Shaun, We just wanted to thank you for all of your excellence and hard work. Our family truly appreciates everything you have done for our son. This has been a life changing event and it would have been different if we wouldn’t have found you. You have given Jake his life back and we can’t thank you enough for fighting for our son. God bless you Shaun, you are truly an outstanding and professional attorney.”


“Dear Jim & Shaun, A heartfelt and most sincere thanks to both of you. Because of your hard work and expertise my daughter has been exonerated! Thank you for believing in her and encouraging her throughout the process and preparing her for the appeals. We wouldn’t have won the case without you!” -R.B.


“Shaun, I cannot thank you enough for all you did for me with my case; it meant a great deal to me.” -A.B.


“After being injured and a car accident caused by another party, I was not sure what my next steps should be yet I knew my injuries were serious enough I should have legal representation. This is when I called GLP Attorneys in Vancouver Washington. The attorney I met with was Shaun Callahan. From my first meeting with Shaun I knew I had made the right decision. Shaun asked detailed questions and took extensive notes regarding the accident. He assured me he would begin working on my behalf immediately and after reviewing my auto insurance policy found additional coverage to help pay for my medical bills. While my case progressed over the next 6 months, Shaun provided me with details of everything he was doing and was always available for any questions I had going forward. His professionalism and confidence was more reassuring. His staff was also on point with communication and any assistance I needed. Shaun was extremely successful in negotiating very substantial settlement offers from both the insured’s company and my insurance company which far surpassed all expectations! There is no question I would highly recommend Shaun Callahan and GLP Attorneys of Vancouver” -S.M.


“Thank you Shaun for everything. You have been very professional and easy to work with. If I ever need another lawyer I will contact you first! Thanks again.” -A.M.

“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.” -T.W.


“My situation was unique in, I was in two different accidents, in two different states three weeks apart from one another and they still took my cases on. They held my hand, explained things so I could best understand it, I was always in the loop, professional to the core and they fought for me when I was in recovery and won! I am forever grateful and have a new family with GLP [Attorneys]!” -A.M.


“Attorney Shaun Callahan and the team at GLP Attorneys are top shelf when it comes to serving their clients needs. Mr. Callahan was very thorough with my case’s and doesn’t settle unless it’s what he thinks is fair. He doesn’t allow the big insurance companies to push him or his clients around. I recommend his and the firms services to all in need of attorney services. Without any hesitation I would use them again.” -C.D.
