Frank Krentz

Frank is a 5th generation rancher in Southeast Arizona.  He grew up in a rural area where he attended a one-room school, and learned the ins and outs of ranching from his family.

Frank attended college at New Mexico State University where he received his Bachelor's and Master's in Agribusiness. After graduating fron NMSU, Frank's first job was with Fertizona Willcox. Soon after, he returned to the family ranch to apply his skills and knowledge from his schooling and hands-on experience.

Frank's family legacy goes beyond ranching. Many of his family members have servered as Supervisors to the Whitewater Draw NRCD; so it was a natural fit for Frank to become involved. Thorughout his childhood, Frank was often involved with conservation projects through the NRCD: brush management, fencing, water improvements, and wildlife-friendly drinkers.

"I hope to help producers throughout the state in getting projects on the ground that will benefit Arizona's natural resources. I believe that by working with our agency cooperators, we can positively impact agriculture thorugh conservation practices and shed positive light on such an important part of our state's economy." - Frank Krentz

Love of ranching, working with the land, and with both cattle and horses is the only life for Shelley and her family.

About 12 years ago, Shelley was asked to take the place of Triangle Supervisor Curtis Ritter when he passed away. If you ask Shelley, she’ll tell you that up until then, she was only slightly aware of what the Districts were about, and that it has been enlightening to learn and participate in their work!
