Heidi Keene
Chairperson, Nursery Liaison

I've been a member of Derry Presbyterian Church since 1986. My husband Jack and I are the parents of two daughters and the grandparents of two wonderful boys. My youngest grandson, Jett, is enrolled in the Ladybug class. Most of my professional life has been spent working in the early childhood field. When my girls were infants I ran a family daycare. I then worked for the Lebanon YMCA for 19 years in both their school-age program and as director of their Children's Center. After that I went to work for Child Care Consultants as a STARS Specialist/Community Outreach Coordinator. Now I am a happy stay-at-home Grandma, watching Jett and getting his brother Noah off the school bus. I was part of the committee that founded Derry Discovery Days. Through the years I have been on and off the board serving in different capacities. Currently I am the church Nursery Coordinator, as such, I serve on both the Derry Discovery Days Board and the Christian Education committee. In my spare time I enjoy painting, crocheting, baking, and travel.


Karen Haas
Elder, Derry Presbyterian Church

I have been a member of Derry Presbyterian Church since 1978. I have served Derry in many capacities, but my most memorable moments have been being a Church School teacher, Vacation Bible School teacher. I am also a member of the Christian Education Committee and Session. I am married to Paul and have two wonderful children (who are both teachers as well) Matt and Emily.  We live in Palmyra where I enjoy gardening, reading, scrapbooking and taking walks with my beloved Black Lab, Abby. I retired in 2015 after a 34-year career as an elementary teacher for the Palmyra Area School District. During my years at Palmyra, I taught ESL, Remedial Reading, Kindergarten, Third grade and Fifth grade. I also have a Degree in Administration earning my Principal certification in 2010. I truly believe that God has called me to help teach, guide and nurture the children of the community and world. I am excited and honored to serve on the Derry Discovery Days Board. I look forward to working with and supporting all the teachers, staff and children of Derry Discovery Days in any way I can.


Jenny Slatt
Parent Representative

We have been part of the DDD family since 2013 when my son, Caden, first attended. My middle son, Jackson, is in the Butterfly class and my daughter, Molly will be starting DDD in 2016-17 school year in the Turtle class. We absolutely love DDD and are so thankful for all the support, guidance, and educational foundation the program has provided our children. Being on the Board is our family’s way of giving back to a program that has given so much.  I have ten years of teaching experience in elementary and middle schools as well as extensive experience working with children with special needs. I have a true passion for working and volunteering in an educational setting. In my spare time I enjoy spending time with my husband, three children, and our dog Della. I love spending time at the beach, reading and capturing my family's cherished moments through photography.

Member of Derry Presbyterian Church & Parent Representative

My husband Greg and I are members of Derry Church. Our oldest son, Landon, started coming to the Discovery Days program at 21 months old in the Ladybug class and is now in second grade at Pine St Elementary in Palmyra. We also have four-year-old twin boys, Hayden and Griffin, who were baptized at church and are now in the Busy Bee Class. I am a stay at home/work from home mom who owns a travel planning business, specializing in Disney vacations, all inclusive resorts and cruises. In my very little spare time (ha!) you can usually find me at the gym or at the rink watching Landon and Hayden play ice hockey. This is my final year on the Derry Discovery Days board and I have enjoyed my time helping shape our program into something amazing!

My family and I have been members of Derry Presbyterian Church since 2017. My two boys will be joining Derry Discovery Days this fall! Gavin will be in the Busy Bee classroom and James will be with the Ladybugs. I am a stay-at-home mom, substitute teacher, and President of the Moms Club of Derry Township. My passion and background is in education and volunteering. I have ten years' experience as an elementary teacher in both a rural and urban setting. I am looking forward to joining the board and contributing to this wonderful program.

Our family has been a part of Derry Discovery Days for two years, as our second daughter attended the Busy Bee and Butterfly classes. Our youngest child, Dickson, will attend the Turtle class this fall. I hold a B.S. degree in Early Childhood Education from Texas A&M University. Before choosing to stay home with our three children, I taught kindergarten and first grade. My experience is in public schools in Alabama, North Carolina, and for a Department of Defense Primary School. I am eager to support the valuable preschool program that DDD provides our community.
