The Pack 133 Leadership Team
(all of our leaders are parent volunteers)
Cubmaster
Eric Toscano
A former Cub Scout and Boy Scout, Eric grew up in Merced County and Sonoma County. He moved from San Francisco to Mill Valley in July 2020 with his wife and two sons—one Lion Scout and one Webelos AOL Scout. Eric enjoys all types of outdoor activities, especially hiking and camping. He is looking forward to his fourth year as Cubmaster—and his second as Cubmaster of Pack 133.
Assistant Cubmaster
Adam Klann
​Adam is Pack 133’s Assistant Cubmaster and previously served as Cubmaster for Pack 3017 in Singapore. A Life Scout and Baloo/IOLS-trained leader, he draws on his experience in scouting and leadership roles to support the pack. Outside of scouting, Adam enjoys photography, skiing, snowboarding, sailing, and cooking. He and his wife Lisa moved to Mill Valley in 2025 with their two sons, Daniel (Arrow of Light) and James (Wolf).
Committee Chair
Melissa A. Jenkins
​Melissa, a proud parent of twin Webelos II Scouts, is serving as Pack 133’s Committee Chair. This marks her fourth year of enjoying Scouting adventures with her twins and husband, Greg—though Rowdy the cat certainly misses them when they’re away! A Mill Valley native, Melissa loves exploring the natural beauty around us and spending time hiking, cooking, BBQing, and sharing family adventures.
Advancement & Events Coordinator/Pack Committee
Sara Halterman
Sara is mom to three Scouts and one very scout-like dog. She has been a Scout leader since 2011 and has worn nearly every hat in the Pack—Campfire Chef, Pinewood Derby Master Engineer, Popcorn Guru, Badge Wizard, Blue & Gold Maestro, Den Adventure Captain, Swag Queen, Logistics Legend, and Volunteer Wrangler. She loves making Scouting fun, memorable, and meaningful, enjoys creating adventures and celebrations the whole Pack can enjoy, and makes a mean dutch oven mac & cheese.
Arrow of Light Den Leader
Erik Halterman
An emeritus Cubmaster, Erik has been a leader in Pack 133 since his son Charlie first put on a Tiger Cub uniform back in 2016. He lives in Mill Valley with his wife Sara and their three children. A Bay Area native, Erik grew up in Half Moon Bay where he was a Cub Scout and Boy Scout himself. He loves hiking on Mount Tam, hunting for mushrooms, painting, and building Pinewood Derby cars in his garage. He’s still up for big adventures—last summer he spent 10 days canoeing 150 miles through the lakes of Minnesota and Canada on a Northern Tier high adventure trip. This year, he’s excited to guide the Arrow of Light den through their final Cub Scout journey.
