Abby Crisco, RDH 

I am from Clover, SC. I joined Dr. Keefer’s practice in October, 2017, after graduating from hygiene school in the summer of 2017. I am honored to be part of his team, a team that shares my values and love of people. I also appreciate the entire team’s dedication to oral health and their willingness to educate their patients on the benefits of excellent oral health.

In my spare time, I enjoy being with my family and my boyfriend. We have two dogs that we adore; Rosie and Zeus. I very much look forward to meeting you!

Pam has worked for Dr. Keefer for over 3 years; however, she has been in the dental profession for over 30 years. She received her dental hygiene degree from CPCC in 1981, and over the years she has had the pleasure of working in various areas of dentistry with some wonderful dental professionals and patients. Pam feels blessed to have been given the opportunity to have such a long-running career in dentistry. For the past fifteen years, she has been a financial and insurance coordinator while still maintaining her dental hygiene license. Pam is excited to be part of Dr. Keefer’s staff because she has found that the staff shares the same values for dentistry as she does.

Pam has been married for 30 years to her wonderful husband, Jerry. They have two daughters, and they love to spend their spare time with them. If she is not working in dentistry or spending time with family, you will usually find her volunteering with her youth group, teaching Sunday school, or being on various committees at her church.
