Staff Cathy Cherre Orthodontics Ellisville MO


Treatment Coordinator

I enjoy working with people of all ages and especially like helping kids feel happy to be here and then helping them change their smiles! I’ve worked in the field since 1983 and been part of the Cherre Orthodontic family since 1994. We are a close-knit group: caring for and supporting each other as we care for our patient family.

I welcome our new patients and families at their first visit. Working with Dr. Cherre, I help explain the treatment process, review each person’s treatment plan and options, and answer everyone’s questions about orthodontics.

My other half is Dan Duffy. I have one daughter, Rachel. She and her husband have given us our young granddaughter, Olivia. Olivia and I love playing Barbies! I also have two Dachshunds, Luna and Lila. Outside the office, I enjoy crafting, scrapbooking, going to movies, water aerobics, and walks with my dogs. I treasure my Catholic faith, enjoy retreats, and serve our community through the Ellisville City Parks Board.

Clinical Assistant

For some people, achieving a great smile can be a life-changing event. It’s thrilling to be part of each patient’s transformation! I found my professional home and family at Cherre Orthodontics in 2002. We all work well together and keep our patients smiling during visits!

I strive to keep patients comfortable during appointments. I take impressions, X-rays, digital scans, and photos. I also assist Dr. Cherre with procedures, bend wires, and fit bands. Additionally, I handle inventory and stocking.

My family keeps me busy during non-work hours. My husband Joel and I have two children, Kennedy and Matthew. I enjoy supporting the children’s various activities, and our family likes camping from spring through fall. Sometimes Tucker, our dog, comes along!

Staff Penny Cherre Orthodontics Ellisville MO


Financial Coordinator

I like watching how each of our patients changes during treatment and seeing the end results. Those beautiful, confident smiles are the best! I joined Cherre Orthodontics in 1999 and immediately knew I was in the right place. We all get along so well, caring about each other and making sure our patients and their families know we’re here for them.

I work in the front office, where I greet and check in patients, answer the phones, and schedule appointments. I also work with patients and parents on financial contracts, to find terms that fit their budget and treatment needs.

When I’m not working, I like being with my husband and my two sons, who are both in college, as well as my two dogs, King and Jackson. I also like crafts, gardening, and outdoor activities.

Staff Diana Cherre Orthodontics Ellisville MO


Orthodontic Assistant / Lab Technician

I enjoy helping patients achieve a beautiful smile that gives them the confidence and happiness they deserve. It is very rewarding to see their excitement and smiles when treatment is completed! I joined this practice in 1989, having started in the field in 1982. It’s amazing to work with people who care about patients like family!

I work in the clinic, where I assist Dr. Cherre with a range of orthodontic procedures and provide patient education and support. I also work in our lab where I make the retention appliances.

My wonderful husband and I have been married for more than 25 years. We have two sons, Joe and Anthony, and a spoiled family dog, Rocky. In my free time, I love to do weight training and yoga. I have been involved in physical fitness for more than three decades, and plan on never stopping! I love the warm weather, beaches, and traveling, too.

Staff Sally Cherre Orthodontics Ellisville MO


Co-Owner / Practice Manager / Married to the Boss!

I love seeing all the great smiles that pass by my office door — from start of treatment to finish, with and without braces! I’ve been part of Cherre Orthodontics since Dr. Cherre and I opened the doors in 1982. I love what we’ve built and that we have a team of great people who really want to do a great job.

I wear many hats at the office. In addition to overseeing the practice marketing, I also solve any and all IT issues, pay the bills and prepare the payroll, and am the HR Department. In short, I’m the go-to-girl for just about anything except clinical work.

I met Mike (Dr. Cherre) at a high school dance when we were both just turning 17. We have been married for 40 years and have three wonderful sons, a really great daughter-in-law, and a beautiful granddaughter. Just ask: I’ll show you a picture, or several!

I have been involved in volunteering and fundraising since 1984 and have been working on ACTS retreats since 2005. I recently co-founded The Palozola Foundation to help veterans. Our mission statement: “Working to heal the body, mind, and spirit of the wounded through golf.”

Staff Mary Cherre Orthodontics Ellisville MO


Clinical Assistant

I love my job because of: cookies, my coworkers, cookies, the ability to work with my hands, cookies, and seeing how people light up when they get their braces removed! (Also, the fresh-baked cookies!) I am the newest member of the Cherre Orthodontics family, having joined in 2017, and love working with a laid-back, faith-filled team to create smiles!

I assist Dr. Cherre with putting on brackets (braces), bending wires, making models, processing X-rays, and taking digital scans. I also take before and after photos and manage our Rewards HUB website, uploading new and fun surveys and contests.

When I’m not working, I enjoy the single life. I like eating sweets, watching Anime, playing computer games, going to the movies, and reading. I’m active in my church and looking at pictures of bunnies and puppies on Pinterest. Oh, and I’m currently having Invisalign® treatment to correct my teeth!
