“I have known Bill Otten for well over 30 years. He was an integral part of selling my dental practice. Bill and Kim brought me only bona fide dentists looking to buy and had my practice sold in 8 days…They made the whole process easy and it was a “clean deal”… It would have been a mistake not to have used their services for the sale of my dental practice.”

Dr. Jon Majers, Des Peres, MO practice

“Bill and Kim are easy to work with and do a very good job- as proof of that, I have bought 3 practices from them and have sold 2! They work very hard to make it a “win-win” transaction for all parties. Because they are local and specialized to dental sales, transitions, and valuations, they know the St. Louis area market and they are always available after the sale to answer questions and solve problems. So, as a “repeat” customer, I recommend them very highly.”

Dr. Todd Wind, South County, MO practice


“After practicing General Dentistry for 43 years, I wanted to be certain my life’s work was positioned well for sale. Kim Rey and Bill Otten kept me posted on all aspects of the sale from listing through closing. I was very pleased with Otten and Rey. They are friendly, professional and they work hard to fulfill the needs of their clients. They are a Five Star organization.”

Dr. William J. Miller, Florissant, MO practice
