Staff at The Arb!

Kris started with The Arboretum in 2006 after a three-year post-doc at Northern Arizona University (NAU) working in a mycorrhizal ecology laboratory. After growing up in New Hampshire, Kris moved to Lexington, KY where she completed her B.S. and M.S. in Biology at The University of Kentucky. She then attended NAU for her dissertation work in piñon-juniper ecosystems. Currently, her research interests include conservation ecology of rare plants, restoration ecology and developing native plant materials for re-vegetation. Kris completed co-editing a technical book in 2012 on plant reintroduction entitled, Plant Reintroduction in a Changing Climate: Promises and Perils, with her dear colleague Dr. Joyce Maschinski. Dr. Haskins lives happily with her husband, two boys, two horses, two dogs and twelve chickens. In her rare spare moments, she enjoys horseback riding, reading juicy fiction novels, and playing with her kids.  Kristin.Haskins@thearb.org

Executive Director

Nate.OMeara@TheArb.org

Nate has always lived by the plants. Growing up in a multigenerational household in Tucson, AZ, his grandfather raised him like a farm kid caring for their family’s two-acre property that felt like their own private botanical garden and natural area. This upbringing instilled a dedication in Nate to spend his life trying to understand the relationship of people and the natural world- particularly with plants!  For over 20 years, Nate has worked as a research ethnobotanist and horticulturist managing public and private gardens in Arizona and Oregon.

Nate holds a master’s degree from Northern Arizona University with focused studies in cultural/environmental anthropology, ethnobotany, horticulture, and ecology. His professional horticultural experience includes working in the nursery industry in both field propagation and sales, as a market permaculture/organic farmer, and as the Curator of Horticulture at the Tucson Botanical Garden. For several years, he also operated his own horticultural consulting, teaching, design and care business. After moving to Oregon, Nate served as a landscape manager and designer where he oversaw the planting and care of a 300-acre master plan development along the Deschutes River.     

Working as an ethnobotanist, Nate has conducted farm restoration projects on tribal lands, state and national parks as well as documented traditional plant knowledge among peoples of the Caribbean, Native American, and Hispanic communities. In an effort to safeguard natural and cultural heritage, he has given scholarly presentations at conferences, authored articles, community publications and technical reports. His passion for education has led him to teach college level courses in anthropology, botany, ecology, environmental psychology and landscape architecture as well as offering numerous community classes on topics related to general gardening, edible and ecological landscaping.  In his free time, Nate plays the Scottish bagpipes and blogs about his garden with his wife. 

Research Botanist

Sheila.Murray@thearb.org

Sheila’s main interests are the rare and endangered plants of the Colorado Plateau, and she contributes to The Arboretum’s mission by collecting, growing, and studying these native plants. Sheila grew up in the small ghost town of Jerome, AZ and has always had a love of the outdoors. She moved to Flagstaff to pursue a career in the natural sciences, and received her B.A. in Environmental Sciences from Northern Arizona University. She has been on the plant research track at The Arboretum since 2001. When she finds free time, she enjoys river rafting, hiking, cross-country skiing, creating botanical illustrations and indulging in other forms of artwork. Most of her free time activities inevitably include botany in some fashion. 

Educational Programs Director

Helena.Murray@thearb.org

Helena came to Flagstaff from Simi Valley, CA to obtain her BS in Environmental Science from Northern Arizona University. While going to school, she worked as an early childhood educator and became passionate about working with children. She is thrilled to combine both of her passions in her role with The Arboretum. She loves the focus on environmental education that The Arboretum provides the Flagstaff community. In her free time, she loves to go on adventures with her husband and two dogs. Helena also enjoys getting into a good book, experimenting with new recipes in the kitchen, and soaking up the sun.

She has a love for wildlife, plants, and everything nature-related! When she is not at work, she is most likely out adventuring with her dog!

Marketing & Events Manager

Jamie.Paul@thearb.org

Jamie grew up in Sierra Vista, Arizona, south of Tucson, and earned her BS in biology at NAU before venturing off to Houston and Denver working as teacher, librarian, nanny, and (randomly) a Six Flags Caricature artist before returning to Flagstaff to work at NAU’s Cline Library. She comes to the Arb from the Flagstaff Public Library and is very excited to support our environmental education, conservation, and research efforts. She has loved plants since her days sword fighting with yuccas, building forts out of yucca stalks, and climbing mesquite trees alongside her brother down in Cochise County. She loves to design things and engage the community through social media, and is looking forward to taking millions of pictures of the plants, animals, and people at the Arb. So, watch out!

Jamie lives with her two dogs, three cats and assorted fish in the cool pines, where she hikes and plays in the woods, gardens in a way that the weeds find quite delightful, plays soccer, writes, draws, reads, plays and teaches piano, dabbles in home improvement projects, and co-directs a little nonprofit called Montessori Forest Adventurers hosting forest enrichment activities for kids.

Greenhouse Manager

Gina.Goegan@thearb.org

Gina has been in Flagstaff since 2008 when she obtained her Masters Degree in Applied Environmental Communication.

Her educational focus is on human’s relationship with the natural world, and she finds herself often pondering all the ways in which we can help this place we call home.

She has a deep love and appreciation for the Colorado Plateau landscape and a perpetual curiosity about all the plants that grow in such a temperamental environment. When she is not working with the plants in the greenhouses she can be found out in the wild with her dog, Ruca.
