About Us 

BOARD MEMBER

Charli Olguin

Charli, a gardener at Blue Moon Community Garden, believes that her unique background can serve as a source of motivation for future gardeners. Coming from a Hispanic migrant farmworker family, she has faced physical challenges due to blindness in one eye caused by a childhood injury, as well as experiencing periods of houselessness. Through sharing pictures and stories, Charli takes pleasure in inspiring others by showcasing how her involvement in CGT has provided her with opportunities to cultivate gardens, foster community friendships, and enjoy the bountiful harvest of fruits, vegetables, and flowers.

Having resided in Tucson for over four decades, Charli has held various jobs assisting individuals in accessing food, which has allowed her to witness firsthand the necessity for communities to have access to fresh produce to supplement their grocery shopping. Charli’s deep connection to agriculture runs in her family, with both of her grandfathers being ranchers and farmers, and her parents having lived on family-owned farms until their twenties and thirties. As migrant farmworkers, her parents relocated the family between California and Arizona in search of employment. In fact, her father even shared stories of planting pecan trees in Sahuarita before Charli’s birth. She cherishes fond memories of her childhood, particularly the times spent picking strawberries in California. The lifelong love for nature and animals instilled by her family has instilled in Charli a passion and reverence for being responsible stewards of the gifts bestowed upon us by Mother Nature.

BOARD TREASURER

Jen Thorn

Jen started gardening with CGT when she and her teenage daughter rented a plot at the Shay-Shay Garden in 2021.  Her service with CGT is inspired by a love of gardening and the belief that gardens bring people together in a positive way, something she has witnessed while working as a “garden mom” in her children’s school gardens and as an educator with Tucson Village Farms.  As a physician and a passionate believer in the concept of One Health (the interdependency of human, animal, and environmental health), she believes that gardens are important places for health and well-being.  Jen currently works as a pathologist and is pursuing a master’s degree in Public Health with a One Health emphasis at the University of Arizona.  She graduated with an MD from Loma Linda University and a BA in Business Administration from Pacific Union College.  In her free time, she can be found gardening, cooking, hiking the Arizona trail with her kids, volunteering with local groups that better the Tucson environment, and supporting her children’s school, music, and sporting events.

BOARD MEMBER

Cassandra Wensel

Cassandra is a Midwest transplant to Tucson and has been active in sustainable lifestyles here for 30 years. Relocating to the Sonoran Desert was transformational and eye-opening for her understanding of the importance of water and land stewardship. Cassandra was active in creating the Keeling Neighborhood Park and Keeling Community Garden during her time as a Board Member of the Keeling Neighborhood Association. She is a retired teacher and curriculum development manager for elementary education and is actively a writer, poet, artist, and healing arts practitioner. As a 500CYT yoga instructor, some of the primary forms of healing she offers are adaptive and accessible yoga and meditation with an emphasis on reconnecting to nature. She volunteers to teach mindfulness to youth groups. Recently having installed rainwater harvesting in her home garden, Cassandra is interested in helping bring these practices to the Community Gardens in the future. She enjoys the music, art, culture, microbrew community, camping, hiking, regional food enthusiasm, and amazing diversity that Tucson has to offer and is happy to serve the community by sharing the joys of gardening.

BOARD MEMBER

Walter Brown

I am a native Tucsonan. I live in Tucson with my wife and also have two adult sons who live in Tucson. I am a local realtor with over 30 years of sales experience. I have always had an interest in plants (growing plants and sustainable vegetation). I have researched chronic illnesses and have found that inflammation (a process common in chronic illness) can be lessened and controlled through a diet rich in plants. I would like to increase outreach to underserved populations improving and promoting their ability for self-care in relationship to health by access to nutritious food.

BOARD MEMBER

Kyla Maciosek

Kyla has been a part of the Tucson/Oro Valley community since 2018 and Arizona since 2013, but was born and raised in Southern Ohio. Her mom was a master gardener so Kyla spent a lot of time outside in their gardens planting sunflowers and (begrudgingly) pulling weeds. She has spent her entire career in environmental education organizations including the Columbus Zoo, Phoenix Zoo, & Desert Botanical Garden. In 2021 she opened her own business, Nature Created Play, where she provides nature play-based professional development courses to educators of young children as well as helps them design and build outdoor classrooms. Kyla is incredibly passionate about getting children outside as much as possible!
