Meet the Team

Meet the Washington Dental Team

Our team consists of an outstanding group of individuals, many of whom have been with the practice for several years. Dr. Mace believes in hiring great people and treating them with respect. As a team, we share a common goal of always doing what’s best for the patient. We love what we do and strive to provide exceptional dental care.

Cooky – Office Manager

A native of the Washington area, Cooky has worked in the dental field since 1973. Before becoming a member of our team in 2000, she worked for three general dentists and an orthodontist – so she’s well versed in the field of dentistry. In her spare time, Cooky likes to play golf and spend time with her grandchildren.


Sheri – Front Office Assistant

Sheri began in the medical field in 1971 and became a member of our team in 2002. She has deep roots in Franklin County and enjoys riding horses and spending time with her grandchildren when she’s not assisting our patients.


Jill - Registered Dental Hygienist

Jill graduated from UMKC School of Dentistry in 1999 with a Bachelor of Science degree in dental hygiene.  She married Dr. Mace in 2000, and they chose to make Washington their home.  A lover of running, boating, and of course, cheese, she and Dr. Mace are having a blast raising their two darling sons.


Patty – Registered Dental Hygienist

In addition to receiving her degree in dental hygiene from Missouri Southern State College, Patty is also a graduate of the Schuster Center for Professional Development where she studied a variety of subjects. Her OSHA and CPR training is current, and she continually exceeds her annual continuing education requirements. Patty holds certificates in nitrous oxide sedation and infiltration and block anesthesia. She is a life-long member of the American Dental Hygiene Association and the Greater St. Louis Dental Hygiene Association. She is also a member of the St. John's Mercy Women's Auxiliary. Patty and her husband, Rick, have two children: one is employed as a pharmacist by Walgreens and the other is in college.  She enjoys the outdoors and time with her family.

Doris graduated from Dental Hygiene in 1990.  She has been a part of the Mace team since 2001.  She is a member of the Greater St. Louis Dental Hygiene Association and completes 45 plus hours of continuing education a year.  She has advanced training and certification to administer local anesthetics, nitrous oxide sedation, and educating patients in dental health.  To add she has studied OSHA Compliance Management Systems to assure staff and patient safety.  Doris takes pride in not only the health of patients but in herself.  She enjoys running, biking,  swimming, being with friends and traveling.  But most of all she loves her two daughters Abby and Emmy!
