Growing up, Dr. Chuck “Jr.” was always around his dad’s periodontal practice. He worked at the office as early as high school mailing letters, calling patients, and eventually working beside his dad and aunts as a surgical assistant. That was enough for Dr. Chuck to decide he wanted to go to dental school, and eventually specialize in periodontics. He is especially proud to work and live in the community that he grew up in and cares so much about!

Dr. Chuck is married to his wife Marissa, whom he met at Maine South High School. They have four children and reside in Park Ridge. When not working, he enjoys being outdoors, and spending time with friends and family. He also enjoys learning about world history and cultures, traveling, golf, and keeping up with local sports teams.
