Office Manager

Ms. Marsha has been a pivotal person in the office. She genuinely cares about our patients and strives to provide the best care possible. She treats everyone with the utmost respect and kindness.


Ms. Marsha is originally from the DC area, but she has been living in Hanover for the past 37 years and has spent for the past 16 years in Dentistry.  She truly enjoys talking to our patients and making them feel comfortable in the office.  




I was raised here in Hanover, PA, graduating from Delone Catholic High School in 1995. I attended Allegany College of Maryland to study dental hygiene, graduating with honors in 1998. I have enjoyed forming relationships while treating patients since joining this practice in 2001. I am married to my husband, Dan and a mother of two children: Evan and Alayna. I enjoy spending time with family and friends, music, crafting, beach trips as well as volunteering at church.




I was born and raised in Hanover, PA. I received my degree in dental hygiene in 2008 from HACC. I joined this practice in 2009 and on my days off have helped out in a few different offices including a periodontal practice. I have a love for patient education and helping patients keep their smiles healthy for a lifetime. When I'm not at the office, I spend time with my husband, our little girl and our rescue pitbull. I also enjoy keeping active outdoors, weightlifting and trips to the beach.


Assistant Office Manager

I’ve been meeting patients as a dental receptionist for the past 8 years.

A smile can change anyone’s day and I look forward to greeting you with a smile at every visit. I’m so grateful for the simple things in life, my husband, our dogs, and coffee.  I’m excited to be a part of this wonderful practice and can’t wait to meet you
