Meet the Team



Practice Manager

Tammy’s job includes a little bit of everything! She is the person who keeps the office running smoothly day to day. She began working for the office in 1980 and Dr. Nicholson inherited her when he came in 1982.

Tammy went to Walker Career Center for her dental assisting training during high school and was able to work at the same time. She loves every aspect of our office, from meeting with patients and parents to working every day with the staff. She says our staff is like a family and we strive to treat our patients the same way.

Tammy has been married for over 39 years and has 3 sons, 3 daughters in law, and 4 grandchildren. She enjoys spending time with her family as much as possible. Tammy also loves camping, traveling, riding bikes, going to Colts games, and spending time with her grandkids and going to their sporting events.



Treatment Coordinator

Tamara is a graduate of IU’s Dental Assisting program. She started working in orthodontics in 1989 and joined our team in 2014. She has worked chairside as an assistant, front desk as a scheduling coordinator, and currently as the treatment coordinator helping guide patients and families through treatment. Most likely, your first appointment will be with Tamara! She says her favorite part of her job is building relationships with the families and seeing the transformation patients go through. Tamara loves working alongside Dr. Nicholson, Dr. Brassard, and her fellow staff because there is genuine care for each and every patient.

Tamara and her husband have four children and two dogs. When she isn't working, Tamara loves to spend time with her family. You can find them outdoors traveling, camping or boating!

Brace Bus Driver

Nancy is one of the first faces you see when you enter our office! Since the beginning of the pandemic, Nancy has been our greeter. She checks patients in, takes their temperature, and seats them in the clinic. She is most known for being our Brace Bus driver which we have started offering as a service again in Fall 2021. Nancy loves working with the patients and getting to know them on a personal level as they go through treatment.

Nancy is married and has two adult daughters and one wild cat. She and her husband have lived in Zionsville for 30 years. Whether she’s walking, hiking, or gardening, Nancy loves spending her free time outdoors. She loves to go to outdoor concerts and botanical gardens. Sewing is also a huge part of Nancy’s life.
