Dr. Victoria Daugherty, Kirkwood, MO

“When I decided to buy a dental practice, I quickly learned that practice brokers represent the seller.  As a buyer, that posed some challenges.  Of all the brokers I worked with in the St. Louis area, Kim was the only one who managed to make me feel that she was actively trying to help me find a practice to buy.  Not only did she help me find a practice that I loved, but she still represented her seller well and was fair throughout the entire process.  Because of her, I am now the owner of a great dental practice that I love and I truly believe she made that happen for me.  Thanks Kim”

Dr. Glenn R. Edwards, West County

“Kim with Otten-Rey Dental Sales truly made what I thought would be a stressfull process extremely easy and painless.  From our first meeting all the way until closing, Kim was always reliably there for me through out the process.  I trusted her system and it was simple and seamless.  I would definitely choose Kim again for my transition if I had to do it all over again.

-Glenn R. Edwards, DMD

Dr. Andrew M. Kim, Hazelwood & Dardenne Pediatric practices

“Kim Rey was my broker represeting me when I recently sold my pediatric dentistry practices.  From my standpoint, Kim brought a great deal of stability to the whole process. I appreciated her insight and her level headed guidance on what my expectations should be, what the normal accepted practice and standards are when dealing with a buyer. The process was longer than I anticipated but Kim kept me focused and on the right track until the transaction was completed.  Throughout the process, She always made me feel like I can rely on her and that in turn, gave me a great deal of comfort.  I would highly recommend Kim Rey to anyone looking to buy or sell a dental practice.”

-Andrew M. Kim, DMD
