Staff & Board

Katherine Bruell learned to love having dirty feet at years of Farm and Wilderness summer camps in Vermont, where she only put on shoes when she was on dish duty or a backpacking trip. She came to New Mexico to go to St. John’s College, where the Search and Rescue Team and trips to Canyonlands and Joshua Tree were highlights of her experiences in the Southwest. Katie says, “I love working at PEEC because I get to use my teaching skills and my administrative skills to help people enrich their lives through the outdoors.”

Since her early childhood growing up in Santa Fe, NM, Kristen has had an overwhelming curiosity about the natural world. Sparked by her parent’s love of gardening and native plants, this curiosity has grown into a burning passion to share the natural world with diverse communities. After receiving a B.S. in Biology at the University of New Mexico, Kristen pursued a career in informal education creating public programs, teaching school groups, and sharing conservation science with communities throughout the east coast at various nature museums, botanic gardens, and conservation organizations from Maine to Georgia to the Hudson River Valley in New York. Kristen joined the PEEC team in 2020 as the Director of Interpretation and looks forward to creating new exhibits and continuing to craft stellar programs! In her spare time, Kristen loves to hike (she’s always on the lookout for herps and pollinators), run, travel, garden, and watch movies (horror and sci-fi are her favorite genres).

Beth spent most of her childhood running around the creeks and forests in Cincinnati, Ohio. Her parents always stressed the importance of volunteering and environmental protection, and it seems like it stuck. The biology department at the College of Mount St. Joseph was able to harness Beth’s outdoorsy nature, infect her with a travel bug, and enable her love of biology. A combination of good memories from visiting family in the southwest and caving expeditions in Carlsbad resulted in Beth moving to White Rock in 2012. She wasted no time getting involved with PEEC, first as a volunteer, then through an Americorps program called Public Allies, and finally joining the staff. Beth loves to get outside and explore and enjoys sharing her enthusiasm for nature, including hiking, caving, camping, and rock climbing.

As a young child, every time Christa told her mom she was “bored” her mom would respond “Well then, you can either play outside or do a chore!” When given the choice, she chose to play outside, exploring the woods and creeks near her house. She also spent most weekends and summer vacations at the lake by her grandparents home or on trips to the ocean. The exposure to water as a child led her down a path of environmental biology with a focus on marine life. Christa worked as a marine biologist in New York, Hawaii, and Australia, studying cetaceans, specifically spinner dolphins and humpback whales. In addition to her research background, she created outdoor education programs and coordinated volunteer efforts for marine non-profits. When she moved to New Mexico it was quite an adjustment! She now loves the dry air, breathtaking mesas, canyons, and bright blue skies. Christa has three children and is thrilled to raise them in such a kind, loving, and beautiful community. Christa joined the PEEC staff in June 2016.

Rachel grew up in Albuquerque, NM and moved to Illinois to study at Knox College, where she was involved in the journalism and environmental studies programs and earned her B.A. in Creative Writing. After graduating, she lived and worked in Sitka, Alaska for a summer. Prior to moving to Los Alamos to work at PEEC, she worked at the Desert Oasis Teaching Gardens at Albuquerque Academy. Rachel enjoys hiking, birding, rock climbing, and spending time outdoors however she can. Rachel joined the PEEC staff in March 2018.

Elizabeth has been camping and hiking basically her entire life. Growing up, every summer was spent camping across the country with her family. She still remembers her first visit to New Mexico 35 years ago where she earned her Bandelier Junior Ranger Badge and ate a tortilla burger in Taos.
