Meriann Manzonelli, RDH

Merriann was born and raised in Dallas. She attended Baylor College of Dentistry and received her Bachelor of Science in Dental Hygiene in 2005. She realized at a young age she always remembered people by their smile and she knew she would have a career in dentistry when she was in high school. She loves caring for her patients and always strives to do her best work on every patient.

When she is not practicing dental hygiene you can find her at a sporting event for her children or for herself. She and her Pittsburgh, PA native husband like to travel and take a yearly summer beach trip with their 2 sons and a daughter. She is always training for her next triathlon, marathon or century bike ride. Next time you’re in the office ask her what she is training for now!
