I started going to RET about 2 weeks ago for tennis elbow. Before I started physical therapy, I could hardly use my arm for anything. It had gotten so bad, just doing the smallest things like pulling off my coat, gave me a very sharp shooting pain down my arm. I can now do a few things without as much pain. It gives me hope that this can be fully resolved without surgery. They were able to get me in within a week of calling. Other places I called had a month waiting list. The staff are all very attentive and caring. I have hypermobility syndrome, so Kris has switched up some of my stretches to better fit my needs. He seems knowledgeable and compassionate. Ben is also knowledgeable and compassionate. They both make sure nothing is hurting me, making sure I'm not over doing it. I am so thankful for RET Physical Therapy at Lake Stevens. Because of them, I have high hopes that I will be able to do everything I could before I got tennis elbow. I highly recommend them to anyone who is looking for amazing physical more

I pulled a muscle in my back and needed physical therapy. I was referred here and had the best experience. The therapists were great and very welcoming. I was able to recover fairly quickly and they gave me exercises, bands and instructions to continue working on strengthening my core, legs and back at home. Highly recommend them!read more

“Two years ago I began to feel pain in my left knee that reached its height when I was hobbling off Mt. Pilchuck in January. I was unable to climb or hike without experiencing sharp pains in my IT band, the fascia that runs from my hip to my knee on the outside of my left leg. I worked with Lauren twice a week for the last two months and am back to climbing, hiking, and walking PAIN FREE! I am not only back to my old self, I fell younger in my joints, hips, knees, and ankles! I haven’t felt so good after a workout since I was in high school. Thank you Lauren for making me feel better! You made it fun too!”-Rocky W.
“It took me about five years to finally admit that I needed to do something about my hip pain and lack of mobility. I finally went to a surgeon who told me I needed my hips replaced, but first I needed to strengthen my muscles surrounding the hips and lose weight. He prescribed physical and nutrition therapy. After the first visit, I was given a few easy exercises to do on my bed, and I was immediately impressed at how how big of a difference it made! I could move better and some movement (like a pivoting) stopped hurting so much. I got great information from the nutritionist and I started to lose weight. I knew that being in the water made exercise a lot easier and less painful, so I asked to start there. I was soon stronger, and I felt so much better; the rewards for my work were so great. The staff was so supportive and encouraging. My first hip surgery is coming up and thanks to Maya, my physical therapist, and Margret, my nutritionist, I am ready. Pounds lighter and much stronger. These guys improved the quality of my life so much, and I am grateful for that.”-Paula M.
“After my total hip replacement surgery I began my PT with RET Reaction Physical Therapy in Lake Stevens. When lying on my side I couldn’t raise my left leg an inch from my right leg! With the help of Kelcie, Kris, and the entire staff I’m doing great. I’m now going to the Team Fitness Gym to get in better health as well. Thanks to my PT, I get stronger every day! The entire team at RET was professional, knowledgeable, and fun to work with. Thanks for everything.”-Mike G.
“Reaction Physical Therapy was terrific.  I worked at both the Smokey Point clinic and the Lake Stevens clinic. Tawny and Amanda at Smokey Point got me prepared to start conditioning, while Kris and Katie at Lake Stevens, worked with me for the work conditioning program.  All were encouraging and very helpful.  I went through a similar injury with my other leg years ago.  When I went back to work, I wasn't ready and reinjured myself.  This time I am more prepared for the job and have returned to full duty with no complications.  Thank You to the whole Reaction family for your hard work and help.”-Derek
