Received great care from Dr. Walters for our daughter. Would highly recommend! She takes time to observe, answer all our questions, and choose the right treatment and follow up. Would recommend her to anyone searching for a pediatric orthopedic doctor.

Dr. Suzanne J. Walters Testimonial

Dr. Walters was awesome with my 3.5 yr old daughter who had nursemaid’s elbow. She was very thorough and did a quick adjustment that fixed it after we spent the previous evening at pediatrics urgent care where they were unable to adjust it properly. I would highly recommend her for kids and adults!

Dr. Raymond Thal Testimonial

I went to go see Dr. Thal about my Tennis elbow and he was great. He gave me a brace to wear when I worked out and told me to tone it down a bit on the weight. I haven’t had any problems since and no longer have to wear the brace after 4 months. He also took the time to look at the bursitis…
