About Us

Tosi and Tosie Dental Background

Dr. Richard Tosie has been practicing dentistry in Arnold for 35 years. Brothers, Dr. Richard Tosie and Dr. John Tosi, started this practice in 1985. John Tosi moved to Memphis to practice for a period of time but moved back to practice alongside family in this great community.

The doctor brothers have spent much of their lives side-by-side so working in the practice together is only natural for them.  They grew up in St. Louis and attended Lindbergh High School.  They went to college at Westminster College in Fulton, MO.  They both also completed their dental training at Baylor College of Dentistry in Dallas, TX. 

 

Dr. Kyle Tosie, Dr. Richard's son, has recently joined the practice as well. Dr. Kyle also attended Lindbergh High School before going on to Auburn University to study business. He later went back to school at Fontbonne University in St. Louis for a degree in Biology before attending the University of Utah School of Dentistry.  This family of dentists is incredibly grateful for the community in Arnold and enjoys serving their patients here!

You may be asking about the slightly different spelling of their last names since one of the doctors spells his with an “e” and the others, without.  When they began practicing together 35 years ago, it seemed the insurance companies couldn’t keep their paperwork straight for each of the doctors, so John dropped the “e” to help avoid confusion. The Tosie family wants to make your visit to their office as easy as possible so reverting one of their names back to their original Italian roots was a simple solution. When John and Richard's family came to the United States years ago, they added an "e" to the end of their name to take on a new legacy in America. Now, their family legacy is dentistry in both forms of spelling.

When you visit Tosi and Tosie Dental, we vow to treat you just like family. We aim to provide a holistic wellness approach beginning with oral health.

Dr. John Tosi

Dr. John Tosi studied beyond the average dental school certification, training in dental and oral surgery at Rhode Island Hospital (Brown University) and Davis Park Veteran’s Administration Hospital (Harvard University). Following, he started the practice alongside his brother, Dr. Richard Tosie, 35 years ago before moving to Memphis. John returned to St. Louis full time with his family in 2017. While living in Memphis, Dr. Tosi was the team dentist for Memphis Redbirds (The St. Louis Cardinals farm team) and the Memphis Grizzlies for 15 years. Additionally, Dr. Tosi was a clinical and endodontic instructor at the University of Tennessee Health Sciences Center. John is also highly involved as a scientific expert on pulmonary medicine and dental sleep medicine. He has been part of many studies and papers, even contributing to two books written by Pulitzer prize-winning author, Ron Chernow.

Dr. Tosi has many hobbies ranging from excavating dinosaur bones to being a major sports fan, he is even an athlete as well! John was a Junior Olympian in the decathlon and studied dance at The Juilliard School in New York. Dr. Tosi is happy to be back in St. Louis with his wife Teresa and daughter Emerson. 

Dr. Richard Tosie

Dr. Richard Tosie started Tosi and Tosie dentistry 35 years ago. After working in the field in other neighborhoods around St. Louis, he chose to open his practice in Arnold for the kind, welcoming community and patient population it offered. Dr. Tosie has always held the philosophy of individualized quality care. His approach is to make sure patients are getting the most out of their time and their money, that they are comfortable and confident with his dental care. Coming from a humble family himself, it has always been important to Dr. Tosie that his patients have all of their options explained to them so they can make their care decisions based on their life, financials, and personal health goals. When asking Richard what guides him as a dentist, he stated “I want to make sure patients are not in pain and that they feel comfortable. My goal is to treat people how I want to be treated in the chair and otherwise, to treat them like family.”

 

Richard has been married to his wife, Ellen, for over 40 years and they have two sons, Richard and Kyle. Their family values are rooted in faith, quality time together, and being serious St. Louis sports fans! They are so grateful for the patients of the practice and that they have trusted Richard with their oral health throughout his career. 

Dr. Kyle Tosie

Dr. William Kyle Tosie, son of Dr. Richard Tosie, is joining the team as our newest dentist. Kyle studied international business, finance, and German during his undergraduate education at Auburn University but later decided to return to school to become a dentist! In 2016, Kyle moved to Park City to attend the University of Utah School of Dentistry. After going through board exams during Covid-19 and a virtual final few months of school, Kyle is ready for anything that comes his way in the future of dentistry. 

Kyle has been around the practice his entire life. He has a “dimple” on his face from running into the office wall as a kid, the same walls he will now come to work within every day. He took out his own tooth at the age of 8 because he knew he could with the example of his dad and John. Kyle is eager to follow in his family's footsteps at Tosi and Tosie Dental. Kyle is happy to be back in his hometown with his wife, Katie, and his two dogs, Bruiser and Beignet. While you are in Kyle’s dental chair, he would love to talk to you about your recent travels, all things sports, and crime podcasts.
