Michelle Registered Dental Hygienist Read Bio

In college I knew I wanted to enter the medical field, and in 1997 when I started as a dental assistant to Dr. Costello, I solidified my choice to pursue dental hygiene. I've worked alongside Dr. Costello for 16 years and in my time here have forged so many great relationships with our patients! Because these relationships were built on trust, our patients enjoy coming back to us time and time again. Now that I am a mother of two, my children Olivia and Chase keep me busy on my days off.
