Dr. Jonathan Koerperick


Dr. Jonathan Koerperick spent his early childhood in Dubuque, Iowa before relocating to Geneva, Illinois at age 9. Since he was a young boy, he wanted to be a dentist. In fact, his eighth-grade career report was written about his dream to become an orthodontist, and this career goal remained throughout his school-age years.

After receiving a Bachelor of Science degree in Chemistry from Illinois State University, Dr. Koerperick attended dental school at the University of Illinois at Chicago. During this time, he discovered that he truly enjoyed the variety of general dentistry. He graduated with a Doctor of Dental Surgery degree in General Dentistry and moved to Arizona soon after.

Before building and opening Raintree Dental in 2005, Dr. Koerperick gained valuable experience working as an associate dentist at various practices in the Phoenix area. These experiences also provided him with a clear vision of how he wanted to manage his own practice. “I’m pleased to offer patients the attention and quality of care that I would want for myself or my family.”

Dr. Koerperick regularly attends continuing education courses and enjoys keeping current on advancing technologies and techniques. “Dentistry has come so far, and treatment options continue to improve significantly. The technology that is now available allows us to detect issues earlier, which means they can be treated more conservatively and safely.”

Dr. Koerperick currently resides in Scottsdale. Together he and his wife have three young children. During his free time, he enjoys mountain biking, off-roading, and spending time with his family. He looks forward to seeing you at your next dental visit!
