Meet The Doctors

Todd R. Holton, D.M.D.

Dr. Holton was born and raised in Montana and attended college at Montana State University and then went on to Dental School at Oregon Health Science University in Portland. After dental school, Dr. Holton moved to southern Oregon and built a large family and cosmetic practice in Medford for the past 26 years; his passion is creating beautiful smiles and healthy mouths. His practice became his second family and his team and patients were with him for many years!

At Montana State, Dr. Holton met his beautiful wife Karen in Medford where they raised two wonderful girls. Their girls found a love for the sun and are now attending the School of Nursing together at Arizona State University in Tempe.

For the past five years, Dr. Holton and his wife have frequently traveled to their condo in Arizona to spend time with their girls and recently made what they refer to as a difficult decision to move where their hearts now belong. They have become permanent Arizona residents and they could not be happier with their decision! Dr. Holton is happy to have found the opportunity at Advanced Dental Health because the feel of the office and team reminds him of the office that he had in Medford.

When not in the office, Dr. Holton enjoys hiking, snow and water skiing, golf and spending time with his family.

Dr. Richard Sinn

Dr. Richard Sinn grew up in a small farming town in Southern Minnesota. He earned his Bachelor’s and Master’s degree in Biological Sciences from Minnesota State University-Mankato (Go Mavericks!). Upon completion of his first Master’s degree he moved to Glendale, Arizona where he obtained his pre-doctoral training and Doctor of Dental Medicine degree from Midwestern University in 2020.

After dental school, he continued his dental education at the University of Iowa where he received two years of surgical training and obtained a second Master’s degree in Oral Health Sciences with research focused on dental implants. He then returned to Arizona where he now works as an adjunct faculty member at Midwestern, teaching first year students. Dr. Sinn’s dental passions are working with students, and restorative practices to boost patient confidence through healthy teeth and gums. He is very excited to join the team at Advanced Dental Health!

Outside of the dental office, Dr. Sinn enjoys going back to visit his home state of Minnesota to see his friends, sister, and nieces Lily and Cora. He is passionate about staying active, coffee and pizza (not necessarily together), sports, and frequenting the dog park with his dog, Chunk.
