We wish to thank all of the SPEE Members who ran for election.  SPEE Board members represent the Society as a whole, generating, defining, executing and supporting various initiatives for growth and progression of the Society.  It is the active participation of the membership at large, and especially, the elected leadership of the SPEE, who continue to make this society highly respected across the industry.  This year, approximately 36% of the membership, down from 39% in 2020, voted in the election.  If you voted, we are grateful for your participation.  If you didn’t vote this year, we encourage you to participate in the voting process next year.

Zack and his wife Beth have two young children and love skiing, hiking, and canoeing.  Beth is a physician and faculty member in pediatric hematology research at Children’s Hospital Colorado.  Having worked in both Houston and Dallas and made innumerable trips to cities like Midland, Tulsa, and Casper over the years, Zack loves pulling over to oil and gas-related roadside attractions to entertain his family with stories of the industry.  They occasionally appreciate it.
