Favorite Activities

Natives of the Pacific Northwest, my wife and I are happy to be back in Oregon to raise our three children. In my spare time, I enjoy running and learning the Korean language and culture. Additionally, I direct the Slocum Sports Concussion Program.  

Patient Reviews

"I am the mother of three late teen/twenty-year old men. Over the years, I have spent a lot of time at Slocum for each of them. I couldn't be happier with this facility, and the doctors we have seen. My son, Garret, tore his ACL his senior year (quite a crushing moment in his life at that time), and Dr. Hoellrich was awesome. He knew Garret was going to pursue the exercise sports and science program at OSU, and made sure that he explained everything in great detail, going above and beyond to help Garret out. We used a local physical therapy place and it was like an internship for Garret. Taron, my youngest, has been in for several things, including a concussion, broken wrist (twice), and shin problems. Dr. Koester saw him, as well as the others, but really made an impression on him.  It was from these experiences that Taron has decided to pursue a career in digital imaging. Gail Wagenblast in radiology allowed him to shadow her and that solidified his choice. Kirk Love was also instrumental in Taron making sure he takes a casting class. Brant, my oldest, broke his finger last summer and needed surgery. Dr. Butters was wonderful. All of the anesthesiologists have been awesome in explaining everything, and making the procedure as pain free as possible. I would prefer that I not need the facility, but how GRATEFUL I am that you are here. Mari Gibson, the athletic trainer at Marist, is what led us to Dr. Koester and Slocum. We appreciate the great person she is, her sound advice, and her leading us to Slocum. Keep up the good work in taking superb care of community!" -- Cinda H.

"After a lifetime of knee problems and four surgeries, I once again found myself with a major problem. Being self employed and cancelled insurance years ago and living on the coast with nowhere to go, I called Slocum Center and got in the next day to see Dr. Koester. After X-rays and evaluating my knee, he said it is in bad shape but a replacement at this time was not the best option. At 59 years old, he said I needed to try and get some more years out of what I have. Plus, the cost is out of my range. He gave me an option for a series of injections that may help me. Then he said let me see if the drug manufacture will help with the cost as it was expensive and he will let me know. In a few days, I got a call with an appointment to come five weeks in a row to start treatment and I was ecstatic to get the help.

Well here I am, three month later doing great. Considering I thought I was done being able to work, I am a contractor and commercial fisherman. I cannot thank Dr. Koester enough for his compassion and the help he gave me. What a rare thing in these times we live in. To all the people at the Slocum Center, I want to thank you for your commitment to excellence in all you do. I am at a loss to say enough. Thank you so much." -- Eric S.

"Dr. Koester was a really nice guy. He helped me with my injured knee. He actually listens to his patients to see what's wrong. Thank you Dr. Koester for your help." -- Daniel C.

"My son Jordan went to see Dr. Koester after he had back problems that kept getting worse. Our family physician referred him, and Dr. Koester diagnosed him with Scheuermann's disease.  He also referred him to the Shriners Hospital for more help.  We appreciate Slocum so much. Jordan was also a patient there three years ago for a hand fracture. It was nice to be able to go where we had been before.  Slocum Center is a very welcoming place to be, and I'm thankful it is here locally for us!" -- Cheryl L.

"Wonderful experience! Lew in the casting room was amazing with my 6-year-old son.  Everything from the greeting to the scheduling was top notch!" -- Corinne Y.

"I went in to Slocum Center for Orthopedics & Sports Medicine because I had a twisted ankle and a broken toe. I found all of the folks very friendly and helpful. I had two visits with Dr. Koester and was released." -- Dennis C.

"Over the past year I have had two major injuries. I broke my right leg; the fibula and just recently I had injured my shoulder. Both of my injuries occurred on my bike, which affected my baseball season. I went to Slocum both times and they treated me with much care and respect. I had trust that they would make my injuries better and I still have trust that they will make them better in the future if needed. Currently I am on my three week mark in physical therapy and I am right back on track to start throwing again. Thank you Slocum for all the work you have put in for me!" -- Thomas N.

"I started cheering in 2011 at the National Academy of Artistic Gymnastics as a class to prepare me for high school cheer. I made the team this year for Thurston High School, starting out on the freshman team. They started talking about moving me up to Varsity during the summer due to my tumbling ability. Then one Friday I was walking in my room and my ankle popped and then it was very painful and I couldn't put any pressure on it. I went to urgent care and they couldn't see anything on the X-ray so they gave me a referral to Slocum Center for Orthopedics & Sports Medicine. The pain went away but we went ahead and got an MRI of my ankle and when the doctor told me that I would be out of cheer for three months and I was very upset. I now have had a cast for four weeks and will be in a walking boot after that. I am missing cheer and will miss most of the competition season, but will be back as soon as possible. I am grateful for Slocum because if they hadn't caught this I could have more problems when I get older and I could have ended up in surgery and missed more cheer." -- Marissa L.
