Alyssa Hosmer has a deep love for community, mentorship, and meaningful connection – all of which come to life at Camp Arbolado. Camp has become a special place where she blends her passion for working with youth, creativity, and leadership into unforgettable summer and spring experiences. Whether she’s mentoring as a counselor/director, organizing/running themed activities, leading games, or simply showing up as a steady, encouraging presence, Alyssa values the joy, growth, and confidence Camp Arbolado helps cultivate in every camper, counselor, and visitor. For her, YMCA Camp Arbolado isn’t just a summer destination – it’s a home away from home, a place where lasting memories, friendships, and traditions are built year after year.”

Vicki Schramm
Camp Native American Program
“At age 11, I had no idea that my first Arbolado camp session would lead to decades of memories that would be treasured well into retirement. There were great years as camper, CIT, and counselor at Arbolado, and also as a director in 1971, at the YMCA’s Day Camp at Tonner Canyon. I thought that a career in teaching would offer summers free to be at Arbolado, and it did. As an elementary school teacher and mom, I returned to Arbolado in 1983 as an adult volunteer with my young daughters Wendy 5½, and Robin, 7. That led to countless summer, winter, and Easter Camp sessions, volunteering as one of the session program directors. I was mostly known then as “Wendy’s Mom”. Wendy and Robin grew up as campers, C.I.T.s. counselors, and summer session program staff. Wendy developed the Native American program, and Robin, the nature program. During the 1990’s, Robin wrote the Camp nature book, Arbolado Trails, and Wendy and I compiled the Camp Devotions Book and song book. I also served 25 years on the YMCA’s Camp Board that became the Camping Services Committee. Camp has taught me the value of life-long friendships, and a deep appreciation of the forest. I will never forget how it feels at Camp to stare into a dark night sky with thousands of stars overhead, or to hear the sound of a hundred kids singing quiet songs at campfire. As an Arbolado Alumni Association member, I want to do my part to insure that Camp will be here for campers and staff for another 100+ years.”
