Jessica Grannum, Assistant Director

Jessica Grannum joined Tamarack in 2016 as our Biking Specialist.  Jess’s passion of biking was evident as she developed our Biking Program into what it is today.  What was once reserved for our oldest campers is now open to campers as young as 1st grade.  Jess created the Learn to Ride Program teaching countless campers how to ride two wheelers and then use the gears, while our more accomplished riders were introduced to our network of trails, learning to do log jumps and challenging themselves on hill climbs.  Summer 2017, Jess joined our Leadership Team as our Munchkin Division Head, overseeing our 3, 4 & 5 year old campers, and started working in the office full time in the Spring. As Munchkin Division Head, Jess oversaw 25 staff members ensuring that all of the campers’ needs were met and communicating camper progress to the parents.  She led the Munchkins to a 2017 Tamarack Cup victory (it is a really big deal).

Prior to joining Tamarack, Jessica owned and operated an Occupational Therapy Practice, which focused on toddlers and school aged children.  Jess is the proud mother of two Tamarack Campers, Joshua and Jason.
