From the moment I walked in, I felt welcomed and at ease. He took the time to listen to my concerns, thoroughly explained everything, and made sure I was comfortable before starting any adjustments. The treatment was incredibly effective—I felt a noticeable difference right away! His professionalism and genuine care for his patients truly stand out. I’m so glad I found him and can’t wait for my next visit. Highly recommend to anyone looking for a great chiropractor! Scott Gregory2025-01-30Trustindex verifies that the original source of the review is Google. I'm trying more to give reviews for local businesses that really deserve it. I don't do it often. This practice is exceptional. Dr. Yaun really listens versus many doctors and practitioners I’ve tried all my life (age 51). With abnormal back pain, I first visited a different chiropractor in town, and upon the first meeting I walked out with a bad taste in my mouth. Not only did they gloss over how much health care would cover (not much, btw), they talked over me and sped me through the admission process. I was like, "I've gone this far in life, why would I choose a practice that doesn't jive? I want a real partner." Of course, getting healed is a process. Nothing’s perfect and there’s ups and downs in recovery. I immediately found that “Spider” takes a thoughtful, practical and pragmatic approach, catered to my (the individual’s) needs, history and goals. For example, I told him first &foremost, I'm a snowboarder, and an aggressive one at that. I do high alpine excursions that are very physical, and what was most important to me was getting my back into shape enough to not miss the upcoming season. He structured a well-thought-out plan that was careful but progressive... eased my fears along the way, taught me why certain things were out of whack...and we figured it all out together. He put me on the right track to success. It should be noted he's an athlete. And that's probably what I liked most... beyond the typical adjustments, he got down on the floor, gave me the proper stretches and exercises for progression and to help me achieve goals. That takes time most won’t do or will rush past. It should be noted his wife, working the front desk, is very well organized, helpful and always has a smile. Being a newbie in town she even helped me find local restaurants and hikes in the area! I can't think of anything Optimal could have done better. You'd be wise to invest your time & money there if you’re hurting. They warn you that the office is difficult to find in the back parking lot – there’s another Yaun in that building - but honestly, just look for the white sign that reads “Spider.” It’s an easy effort.

Dr. Yaun is extremely knowledgeable, and patient when explaining your treatments. I was very nervous about getting adjustments and he has made me very comfortable. My hip and back pain is already improving after a few weeks. Lindsay Gadzik2022-05-23Trustindex verifies that the original source of the review is Google. Effective, targeted treatment! Dr. Yuan explained his findings & recommendations so clearly, and his practice offers very flexible hours for working professionals. Dr Yaun’s adjustments feel like small miracles. I’ve seen improvements in my range of motion in just a matter of a few short weeks :) Kayla Shay2022-04-04Trustindex verifies that the original source of the review is Google. I started going to Dr. Yaun for my shoulders that had been bothering me for years. Everyone was very friendly and nice. I am a very shy person, but talking to Dr. Yaun and his wife at the front desk is easy. Dr. Yaun's correction sessions helped get the tension and stress out of my back, neck, and shoulders. After Dr. Yaun recommended that I work with the trainers available on sight to strengthen my muscles in my shoulder area. The trainers were also very friendly and their workouts helped to straighten and stretch out my shoulders. If you are thinking about going to a chiropractor I would highly recommend Dr. Yaun's practice. TARA SHAY2022-03-21Trustindex verifies that the original source of the review is Google. My experience with Optimal Sports Therapy has been life changing. I was referred to Dr. Yaun with intense lower back pain that was reoccurring despite physical therapy. I was nervous to make the first appointment, but Dr. Yaun and his staff made me feel comfortable and safe. He was able to assess the source of my pain and create a care plan that demonstrated expertise in his field. Each adjustment helps me maintain an active lifestyle and release the stress I tend to store in my body. It is easy to make appointments and they are always on time. For all of these reasons and many more; I highly recommend Dr. Yaun. anthony gillard2021-12-15Trustindex verifies that the original source of the review is Google.
