"We are pleased to have Mark join our staff," said Robert F. Kanaby, NFHS executive director. "Mark's background in meeting planning, corporate development and sport administration with the NMAA is a perfect fit for this position on our staff."

As the NMAA's director of corporate development the past four years, Koski helped the organization increase its annual corporate sponsorship revenue from $27,000 to $700,000. He also was instrumental in starting the NMAA Foundation, which raised more than $100,000 in its first year of existence.

Koski also served as the NMAA's conference and meeting planner, including the Annual Meeting of Schools, the New Mexico High School Coaches Association Annual Coaches Conference, the New Mexico Athletic Directors Association Summit, the New Mexico Officials Association State Clinic and New Mexico's first Steroid Summit, held in conjunction with the Drug Enforcement Administration.

In addition to meeting planning and corporate development, Koski has served as administrator for the sports of swimming and diving, track and field, and cross country. In cross country, Koski introduced the chip timing system for scoring, and he created "sport-specific manuals" for all NMAA sports.

Koski graduated from Highland High School in Albuquerque, New Mexico, in 1995. He earned his bachelor's degree in physical education from the University of New Mexico in 2000 and his master's degree in sport administration from UNM in 2003. As a member of the National Interscholastic Athletic Administrators Association (NIAAA), Koski earned his Certified Athletic Administrator (CAA) status in 2005 and his Certified Master Athletic Administrator (CMAA) in 2007.

Prior to joining the NMAA, Koski was a physical education and special education teacher at Manzano High School in Albuquerque for three years. He served as head track and field coach at Manzano for one year and was an assistant football coach for three years and assistant track coach for two years.
