Janet Voll

My name is Janet Voll and I have been working in the field of dentistry for 33 years in Columbus, Indiana. I have been married for 25 years to my husband, Jim, and we live on a mini-farm with chickens, goats and LOTS of cats. I have two grown children and 4 beautiful granddaughters who are the lights of my life. Working with Dr. Barr allows me the opportunity to help our patients work through their fears about dentistry whether it be physical, emotional or financial. My goal is to make sure every patient, young or old, leaves here with a happy, healthy smile on their face.

Shelly Ritchie

I can remember telling my middle school guidance counselor that my life goals consisted of being a mother and dental hygienist. I can honestly say I’m living my childhood dream. My two little girls are the reason I wake up in the morning. They are my heart and soul. I am also the nursery director for our small church. Children are amazing because they bring a lightness to life that we, as adults, often miss. I graduated from the IU School of Dentistry in 2005 and have always loved my career. There is a real sense of satisfaction when patients leave our office smiling. For our office, it’s not just about dentistry – it’s about the person. Our patients are like family and we get the opportunity to learn about their lives. And yes, sometimes it’s even with their mouths wide open. I look forward to meeting you, as well!

Shayley Brewer

My name is Shayley Brewer and I have worked with Dr. Barr for about 1 year. I am a Columbus North graduate and Ivy Tech trained dental assistant. I enjoy spending my spare time with my 3 dogs, friends and family. I enjoy my job because it challenges me to learn the new concepts of dentistry. I love meeting our patients and helping them be comfortable during their treatments. I love the warm, nurturing atmosphere in this office and the fact that Dr. Barr takes his time explaining procedures and educating his patients. My goal is to help patients achieve the best dental care available.
