Meet Tammy

Tammy O_Brien

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.
