THORPEWOOD STAFF If you would like to contact a member of ThorpeWood’s staff, please call 301.271.2823

Sam Castleman

President/Executive Director

Sam grew up in North Carolina. He attended the University of Washington, School of Forest Resources, and earned a BS in Forest Management. Sam arrived in Frederick County in 1995, when he began his work as Executive Director of ThorpeWood.

Sam’s greatest work pleasure over the last 25 years is that ThorpeWood is recognized not merely for its timber-framed Lodge, its farm animals, its arboretum, its spring-feed mountain stream and pond but more significantly as a place where a community of folks who identify ThorpeWood as a place of safety, comfort and growth opportunities consider it their “place”. This fact coupled with our effort to give the ThorpeWood experience mainly to those who are the least likely to have such an experience makes our work sweetly rewarding.

Sam is married to Julie whose company, Mountain Memories at ThorpeWood, runs all events on the ThorpeWood property. Julie has been part of the ThorpeWood experience since our doors opened in 2000. Aside from being his best friend and life partner, Julie in her inimitable way has been central to ThorpeWood’s development of “community” as all who know her even in the slightest would readily agree. Julie and Sam immensely enjoy spending time with family, cooking, kayaking and exploring our beautiful USA.

Jeff Isaac

Property Manager

Jeff is a graduate from University of Pittsburgh Johnstown with a degree in Marketing Management. He started working at ThorpeWood in March 2019 as Assistant Property Manager, and within a few months, he was promoted to Property Manager. Prior to ThorpeWood, Jeff worked in the pool industry for twenty years. He’s enjoying the change of scenery, the various job responsibilities, and the challenges that come with maintaining a 160-acre farm. In addition to his job as Property Manager, Jeff assists the other programs on the farm as needed – Head Start and Mountain Memories at ThorpeWood. Working at ThorpeWood has been, and continues to be, an amazing learning experience!

Jeff and his wife, Katie, got married at ThorpeWood in October 2016. They have a son, Luke, who was born in 2018. In his free time, Jeff enjoys spending time with his family, fishing, playing tennis, watching sports (Go Nats!) and playing numerous musical instruments.

Katie Guth

Program Director

After being raised on a farm in New Jersey, Katie migrated to Pennsylvania to attend Gettysburg College, from which she received her B.A. in Sociology, with accompanying minors in Education and English. As part of that education, she interned at ThorpeWood and afterward refused to leave. And so, in time, she was adopted as one of the farm animals, a barefoot creature who subsists on mud and sunshine. Given these muddy roots, Katie is passionate about bringing children and adults alike into her world of buttercups and bugs.

On the home front, Katie and her husband, Alec, cohabitate with a variety of cute creatures, including a small pack of dogs (Ruby, Chester, and June) and two little girls (Josie and Ivy).

Katie is a certified forest therapy guide through The Forest Therapy School.

Mattie Hoover

Barn Manager

A local to the area, Mattie grew up in Hagerstown, Maryland. Having relocated to Frederick with her husband in 2021 to be more local to work, she stumbled into the role of Barn Manager at ThorpeWood in an effort to change tracks from the biotechnology industry, where she worked for 2 years after obtaining a bachelor’s degree in Biotechnology from the University of Maryland Global Campus.

Mattie has two passions: animals and helping others; which makes every day in her role at ThorpeWood a dream come true. When she isn’t grooming and riding the horses, or playing with the goats, she’s helping Katie teach any visitors about the wonders of nature and farm life, or she’s helping Jeff with property maintenance (seriously, 160 acres is A LOT!).

Mattie and her husband, Chris, enjoy chilling at the dog park with their senior Boston Terrier, Frazier, and watching the newest season of Bob’s Burgers in their spare time. She’s also a devoted nerd, reading comic books in her spare time, as well as other books that continue to fill up her home library.
