Leda has two boys, Andrew and Anthony, and enjoys spending time with family.


monique – dental assistant

Monica Rosales, better known as "Monique" in our office (to avoid confusion), graduated from dental assisting school locally in 2017.  As part of her year-long curriculum, she accumulated the necessary clincal hour by perfecting her skills at Greenstein Dental both chairside and in the dental laboratory.

Originally from Barranquilla, Colombia, Monique got her degree in Pre-School Education from Santiago de Cali University, teaching for many years there before coming to Florida.  She continued with Pre-K education in Miami after receiving her CDA license from Miami-Dade College.  The combination of experience with children and her interest in dentistry allowed her to seamlessly blend in with the pediatric part of our practice particularly assisting in orthodontic care.

Married for over 23 years to her US Coast Guard husband, Rafael, she enjoys spending time with him and her son, Matthew, particularly traveling.
