When Dr. Ryan Diederich decided to start his practice as a Board-Certified Plastic Surgeon about 20 miles from St. Louis near Maryville, Illinois, the choice was easy. As a Southern Illinois native raised in Marion, Dr. Diederich says, “It was the community that made my decision to return to Southern Illinois. This region has provided us with so many opportunities. The people of the Midwest and their values helped make me who I am today. Being able to give back to the community is important.”

What Sets Dr. Diederich Apart in St. Louis?

For residents of the area, including Springfield, IL, who often think they have to travel to St. Louis for cosmetic plastic surgery, Dr. Diederich provides the experience and technical skills of “big city” plastic surgeons in the comfortable and relaxed environment of Glen Carbon, IL.

As a result of his extensive training and experience, Dr. Diederich has developed a keen understanding of how to achieve natural results while still enhancing his patients’ appearance. He also understands how important it is that patients feel comfortable with their choice of surgeon and trust them implicitly before undergoing cosmetic surgery. He meets with each patient personally before any surgery takes place so they can get to know him better and feel more confident about their decision to go forward with their procedure.

Dr. Diederich earned his medical degree from Southern Illinois University School of Medicine and then completed an intense 6-year residency in Plastic & Reconstructive Surgery in Springfield, Illinois. This training covered all areas of reconstructive and cosmetic plastic surgery.
