She found exactly what she wanted for him at ECC with the play based school with a loving, nurturing, and talented staff.  She immediately registered him and soon became part of the staff she so admired. Ann started out at ECC as a substitute, became an assistant, and then worked as a teacher for ten years at another preschool. Ann grabbed the opportunity to come back home to ECC as a teacher in 1998. She taught the three year old class for 15 years and in her "retirement" found her niche as an assistant at ECC once again.

Denise Harvey-Lead Teacher

Denise grew up knowing she was very interested in working with children.  She graduated from college with a degree in Guidance Counseling.  After moving to Arizona, her career goals shifted to Recruiting and then Human Resources where she focused on being trustworthy, honest, and detailed.  When she and her husband welcomed their daughter to their family in 2010, staying home to raise her was the number one priority.  In 2013, the Arizona Harveys moved to Rockville with the desire to be in a diverse city as well as to be closer to family in New York.  

In researching preschools for her own daughter, she saw various philosophies and heard feedback from other parents on what worked and didn't work for them depending on their child, discovering that even siblings might have different learning environment needs.  As a classroom volunteer and co-op parent, she learned so much from other parents and the children she worked with.  As children are learning to communicate and develop their social and emotional skills, she believes it is important for teachers and parents to communicate in order to provide a strong continuous foundation to support learning.  

She is excited to work at a school that promotes those building blocks and she is dedicated to being a positive, compassionate and supportive role models for families.
