The teacher is the designer of the child’s environment and maintains the rhythm of the day. He or she constantly interacts with the children and is engaged in an ongoing cycle of observation, guidance, and assessment. The relationship that the teacher develops with each child is instrumental in providing the safe and secure environment on which OCP prides itself. The teacher also helps children work through disagreements as an unbiased mediator.

Another important relationship that the teacher nurtures is the relationship with the parent. Open communication with parents occurs on a regular basis, and the unique parent-teaching experience of the cooperative preschool allows for an even stronger relationship between parent, teacher, and child.

Relationships between caregivers/teachers and children and their families are the foundation of a child’s development of sense of self and security and his or her ability to relate to others and express feelings. Our low child-to-teacher ratio fosters this strong relationship between teacher, child, and family.

Every class at OCP is led by an experienced teacher with at least a bachelor’s degree in Early Childhood Education or related area of study and extensive experience working with young children and parent education. Lead teachers are supported by a parent-teacher, and in the case of the oldest class—the Larks, an assistant teacher. Assistant teachers must have successfully completed an associate degree in early childhood education with three to five years experience or a four-year degree with one to two years experience.

All teachers undergo an extensive interview process to determine their professional and ethical understanding of teaching young children. They must also understand and respect the parent’s role in a cooperative and value parent education. All are required to have current CPR and first aid certification.

Melissa Ogliastri - Bluebirds (older twos), Chickadees (young twos)

A Massachusetts native, Melissa Ogliastri moved to Charleston, S.C. to attend Charleston Southern University, where she graduated with a BS in Early Childhood Education. In 2009, Melissa relocated to Atlanta to be a nanny for her nephew and two other children. Coincidentally, the children were all OCP alums. During those years, she came to appreciate the school’s child-led, nature-based curriculum. And seeing how they’ve continued to thrive socially and independently has been a very powerful confirmation.

Melissa is very excited to be the Bluebird’s and Chickadee’s teacher this year. She served as the Larks assistant teacher for the previous two years and learned so much from Margie a skilled, experienced teacher. Melissa is confident children will have very meaningful experiences at OCP.

She lives in Atlanta with her husband, Andres, and daughter Samantha.

Susan Diamond Sparrows (threes)

Susan Diamond has been involved in cooperative preschool education for fourteen years. She has a Bachelor of Arts Degree from Georgia State University, with a major in French. After completing college she was employed in the hospitality and restaurant industries, which allowed her to pursue her interest in travel.

Soon after Susan became employed there as a substitute teacher, after-care teacher, and teacher’s assistant. She then became a teacher and taught a multi-age class of three- and four- year olds.
Susan believes that children at the preschool level learn through play, and from experiencing and exploring the world around them. She feels that having parents present to participate and contribute in the classroom fosters a strong sense of community.

Her daughter is a junior at Drew Charter School and has an incredible enthusiasm for learning, which Susan attributes to early school years at a cooperative preschool. This is Susan’s eighth year as the Sparrows’ teacher. She enjoys playing a positive role in the lives of her students here at OCP.
