...Mark Bowman is Retiring.
After 40 years as a public school teacher and 25 years as co-director of the Earth and Space Science Laboratory, Mark will retire on June 30th, 2014. 

During Mark’s tenure at the ESSL/Planetarium, tens of thousands of students, parents, and other adults have participated in their school’s visit to the ESSL or attended one of the 1500 evening programs that Mark has helped provide. 

His work ethic, dependability, dedication to his colleagues, the facility and program, and commitment to the students and community have been commendable. It has been stellar!

Mark is the ‘Cal Ripken’ of FCPS!

Throughout the next few months as you visit the ESSL for an evening program, or with your child’s class, please thank Mark for his year’s of service to the Frederick County Community.
