Courtney Lupo

Courtney has a degree in Early Childhood development and has worked in the field for many years as a preschool lead teacher and then as an assistant director before becoming a stay-at-home mom. She currently lives in Wappingers with her husband and three boys, who are all in Wappingers Central schools.

When not at NHNS, Courtney can usually be found on the baseball field or basketball court, where her boys are involved in many travel sports.

Kristen taught 3rd & 4th grade in the Minisink Valley school district & 1-5th grade at Orange-Ulster BOCES in Orange County.

When she is not working, you can find her at the soccer field with her son, watching her daughter at dance class, or trying to sneak in a few pages of a good book! 


Kristen is extremely excited to be part of the New Hackensack Nursery School community and teaching in the 3’s program.

Debbie Muesser is a graduate of Iona College with a Bachelor of Arts degree in English and Secondary Education as well as a Masters Degree in English.  She taught middle school and high school in the Bronx until she had her first child and decided to stay home to raise her family.

All three of her children are alumni of NHNS and she volunteered for six years on the NHNS Board of Directors. After her children graduated from NHNS, she loved the school so much and wanted to stay involved so she became a substitute teacher.

Originally from Staten Island, she moved to the Hudson Valley with her husband in 2002 and is quite active in the Wappingers community. She has been a member of the CYO Board of Directors for St. Mary's of Wappingers Falls and coached basketball for multiple age groups (Kdg.- HS).  She has also been a team mom for one of the SD Patriots Football teams and has coached T-ball and softball for TOWLL.

When she is not teaching at NHNS, you will find her on a basketball court or sports fields with her family.  She loves spending time with them and vacationing in Disney World. Her hobbies include interior design, gardening, crafts and reading.
