Karen Gresham
President
Phoenix
Karen is a third generation Phoenician and has spent most of her life living near and hiking in the Phoenix Preserves (Piestewa Peak). She graduated Summa Cum Laude from Arizona State University, earning a BS in Accountancy and minors in Spanish and Communication. After working as a CPA auditing all types of companies from large corporations to nonprofits to utilities, she “retired” from accounting to raise her three sons. Ever since then Karen has volunteered her time in the classroom, helping public education candidates, and for many charitable organizations. She has raised over $100,000 for the Leukemia and Lymphoma Society and is now on the leadership team. She currently serves as an elected governing board member for the Madison Elementary School District, and coaches cross country for one of the middle schools. Karen loves everything trail related; she has completed several trail and ultra-marathons in Arizona and beyond, and is a trail steward/hike patrol for the City of Phoenix Parks Department. She has been on many parts of the AZT and will complete a thru-hike eventually!
Dana Ernst
Vice President
Flagstaff
Dana moved to Flagstaff in the fall of 1997 to attend graduate school in mathematics at Northern Arizona University, where he is now a professor. While rock climbing is the first outdoor activity that got him into the wilds of Arizona, he has enjoyed many immersive experiences while mountain biking, trail running, and backpacking. Dana and his wife have two energetic sons and a dog, and as a family they hike, bike, and run the trails throughout Arizona. He believes that respect for sensitive habitats and places of cultural significance are what make trails truly sustainable, and the Arizona Trail is the crown jewel of our vast networks of trails. Dana is honored to play a role in preserving the AZT, as well as enhancing it for his children and future generations. He has served as a Bikepacking Roots Regional Advisor and is active within the NAU Cycling Club.
David Rabb
Treasurer
Tucson
David first visited Arizona in 1978 and immediately fell in love with the wide-open spaces, beauty, and diversity of the desert. In 2004, he moved to Tucson which has truly been home ever since. His involvement with the ATA started later that year; volunteering in the construction of the Cienega Corridor near Vail. He has continued building and maintaining the trail ever since, participating with the Crazies, Usual Suspects, and Tom’s Sawyers. In 2010 David began segment hiking the trail, completing it in 2012. More recently, he has also had the privilege of participating in the Trail Angel program. David loves to meet trail users from across the world and learn their stories. He believes the trail itself is a wonderful place, but the most important things are the benefits it brings to the people who experience it.

Shawn Redfield
Board Member
Pine
Shawn’s volunteer involvement with the ATA began in 2005 with remote trail construction along Passage 15. After 30+ years of bureaucracy working for the Department of the Interior, Shawn retired from public service in 2010 and decided to unwind by hiking the AZT. Since then he has continued to work on many areas of the trail including the layout and design, construction, maintenance, and infrastructure development. In 2011, he formally took on the role of Director of Trail Operations where you can witness his unwavering commitment to the continuation of developing and maintaining the trail. Whether he’s installing a sign, replacing a gate, or conducting trail work, Shawn is always busy supporting staff and volunteers to see that they have the tools, supplies and the where-with-all to do their part. He received the 2015 Trail Volunteer of the Year Award from American Trails, and in 2016 was named the Cox Conserves Hero for Arizona – an award that honors volunteers who create, preserve or enhance the outdoor places in our communities.

Rebeca Rodriguez

Phoenix
Rebeca’s Arizona Trail journey began in 2018, sparked by volunteering at a trail reroute event in Happy Jack. Witnessing the transformative power of community, she made it a goal to give back to the trails, accumulating over 200 volunteer hours on the Arizona Trail. In 2022, she was selected to be a part of American Hiking Society’s NextGen Trail leaders program where she refined her leadership skills by actively engaging in state and federal trail advocacy efforts.

Prospective Board Members
Pablo Burghard
Globe
After a 27-year career in finance at Merrill Lynch in Texas, Pablo moved to Arizona in 2000 to pursue his passion for river rafting on the Salt River. Since the river season can be short in Arizona, he began to volunteer to do trail work for the Tonto National Forest. Pablo quickly failed retirement as his volunteer work morphed into part-time, then full-time work over the next 15+ years. “Learning by doing” taught Pablo trail layout, new construction, ongoing trail maintenance, post fire rehabilitation, grant writing, youth crew management, and working with volunteers and partners. Eventually, his job grew to managing all of the 1,000 miles of trails on 3 million acres of the Tonto National Forest. This included extensive work in partnership with the ATA over many years. The ATA recognized Pablo with the Larry Sneed Trail Stewardship Award in 2010, the Outstanding Partner Award in 2015, and the one Pablo is most proud of – the Lifetime Achievement Award in 2019. Pablo hopes that his experience on the trail and knowledge of fiscal management will help sustain the ATA for generations to come.

Alex Derr

Tempe
Alex moved from Oregon to Arizona with dreams of bikepacking the Arizona Trail. He soon found he enjoyed working on the trail as much or more than biking or hiking it. After thru-hiking the AZT in 2021, Alex became a trail steward in the Mazatzal Wilderness. He enjoys hosting annual work trips in the Mazzies and organizing groups to re-open and maintain neglected trails connecting to the AZT. As a mechanical engineer, Alex spent 20+ years designing oceanographic instruments and supporting scientists studying global change. Now volunteering for his partner’s lab at ASU, he supports ecosystem research in drylands. He loves being outdoors and appreciates having access to our extensive public lands.

Since moving to the desert, he’s been dedicated to improving healthcare access in underserved communities across Pinal County as a clinical pharmacist in Florence and Oracle. He specializes in chronic disease management, patient education, and developing continuing education for his peers. But when the workday ends, Jacob is all about the great outdoors. An avid hiker, backpacker and cyclist, Jacob quickly fell in love with the stunning diversity of the Sonoran Desert. His passion for the wilderness runs deep; what began as a simple love for hiking evolved into a commitment to preserving the very trails he hiked. Inspired by the Backpacker Radio podcast, he started volunteering on the Arizona Trail and soon completed the Trail Skills Institute.

With over 750 volunteer hours logged, Jacob is committed to protecting these landscapes for future generations. His work focuses on trail maintenance and educating fellow outdoor enthusiasts about the importance of conservation and responsible recreation. Whether he’s providing education on chronic disease management or clearing trails, Jacob is driven by a single goal: to give back to the places that bring him peace and the thrill of adventure.
