Dr. Sostak was very professional, calming and reassuring that my arm surgery would go well. His explanations were clear, understandable, and thorough.

Dr Sostak is very kind, understanding, and demonstrates a high level of professionalism. I had a very pleasant experience with Dr Sostak and his team throughout my pre-surgery procedures as well as post-op procedures. I highly recommend Dr Sostak for any Orthopedic care.

Dr. Sostak was phenomenal. He was calm, collected, composed, & communicated his professional opinion of dealing with my knee injury in a confident manner. Confidence that provided peace of mind & steered me in the right direction of proceeding with the reparation procedure.
A day after the procedure and now having seen the before and after pictures of the damaged and repaired meniscus. There’s not a doubt in my mind that Dr. Sostak and Fox Valley are the best in the business. On a difficult day, their entire outpatient team made the journey as quick and comfortable as possible.
Stay tuned for the 6-12 month full story review after physical therapy…A time that I hope to be back on the ski slopes or the golf course, and planning to build a statue to honor both Dr. Sostak & Dr. Bartel

Dr. Sostak personalizes treatment to meet the needs and goals of each individual. He takes a multidisciplinary approach to patient care including non-surgical treatments such as focused physical therapy, anti-inflammatory treatments including injections and orthopedic biological therapies such as PRP (platelet rich plasma). When non-surgical treatment won’t solve the issue, he is well trained in orthopedic surgical options.
