Kimberly Butler, RDH

Registered Dental Hygienist

I have a degree in both Science and Dental Hygiene through Mount Wachusett Community College. Being a pediatric dental hygienist has always been a childhood dream. I particularly like working for Concord Children’s Dental Associates because of the various different circumstances and need for each patient. Whether it be a patient who has or needs orthodontics, an anxious child to help encouraged through their appointment or a special needs child, I’m always prepared to meet whatever the need is of the patient. I am a lifelong learner and am always looking to see how I can grow in any aspect of life. Outside of work, I like to use my energy doing CrossFit, hiking, running, and biking.


Kip Paillard

Office Coordinator & Senior Certified Dental Assistant

I’m a mother of 3 beautiful kids who keep me very busy with all the sports they are involved in. When not working I enjoy camping, fishing and any activity that allows me to enjoy nature.

When I’m not enjoying the outdoors I have the greatest job ever, and that is to create charming smiles for all ages! It is such a privilege to be part of such a big event in a patients’ life! The relationships I’ve created with each patient and their families has always been a journey filled with laughs.

I look forward to many more beautiful smiles!
