Sandy Costello

Office Manager

Hi! I am Sandy, the office manager for Fenton Family Dentistry. I graduated from Missouri College in 1997 and received my Expanded Functions license in 2010. Being in the dental field for 21 years, I have seen a lot of changes in the dental field. Fenton Family Dentistry is using cutting edge technology to take their dentistry to the next level, making me fall in love with dentistry again! I strive to make every patient feel at ease and do whatever it takes to make your visit a fabulous one. My goal is not only make each visit go smoothly, but also make each patient feel at ease and build a lasting relationship. I have been happily married to my husband since 2009. With our 2 daughters all grown, we are enjoying spending more time together. When I am not at work, you can find me doing a wide variety of things: photography, refinish furniture, camp, fish, hunt, and ride ATVs.


Brittni Reich

Patient Concierge

Hi, I'm Brittni I am a part of Fenton Family Dentistry's awesome front desk team. I found my passion for dentistry two years ago when I joined this amazing dental team. I am constantly learning and challenging myself every day. My position is to help patients understand their insurance and financially responsibility. We want each and every patient to understand that their oral health is important and we are here to help them anyway we can. We love to see patients completing their treatment and knowing that I was a part of that journey is very rewarding. I have a great supporting team at home as well. My husband Jacob and two giant fur babies Jax and Kylee.  They keep my life full of love and laughter. We enjoy venturing out together as a newly married couple and hope to start a family in the near future. My job brings a smile to my face even through the toughest days. There is no doubt that I will work hard to be the best that I can be. I am very honored to have the opportunity to help make Fenton Family Dentistry a warm, comfortable and exciting place to brighten your smile!


Paige Borzillo

Patient Concierge

Hi! I am Paige. One of Fenton Family Dentistry’s front staff members. I discovered my love for dentistry early in life. I always looked forward to going to the dentist and had so many fond memories being a patient in my pediatric office. I feel that it is my mission to help make everyone feel comfortable and stress free when they come into our office. When I am not at the office, you will most likely find me somewhere outdoors. I like to try and stay active by hiking or biking. One of my favorite things to do in the summer is to go boating and water skiing down at Table Rock Lake with my family.



Katie Carpenter

Insurance Coordinator

Hi, I am Katie, I am the Insurance Coordinator for Fenton Family Dentistry. I have worked in the dental field for 8 years. I graduated from Missouri College for dental assisting and ended up at the front desk pretty quickly in my career and I fell in love with it. My passion is Insurance. There is so much information, I am always looking for new ways to better educate myself. I love to learn how a plan works, what changes are being made, and most importantly how I can help the patient utilize their benefits. When I am not at work I love being with my family. I have been married to my husband for 11 years and I have two children, Olivia and Xander. There is a good chance you will find me reading at any opportunity that I get.
