Vice President

Jack Haskel

Pacific Crest Trails Association

Jack first discovered SNTMA through being a bike commuter from Midtown to South Natomas. He became his office's commute coordinator and is always eager to encourage his coworkers to take advantage of SNTMA's excellent programs, from carpool benefits to Bucks for Bikes. At his office, he has helped secure SNTMA support for secure bike racks, an office share bike and other benefits.

As a board member, I'm proud to help oversee and guide SNTMA's work. I'm a strong believer in doing what we can in South Natomas to reduce the amount of air pollution and traffic congestion that's caused by so many of us driving alone to and from work. SNTMA has an extensive suite of programs to help you protect our air. Take advantage of them!
