Throughout that time he has helped to expand the use of video and digital audio for learning and performance documentation for the MMB. One enjoyable aspect of being part of the MMB video crew for Robert has been the level of commitment and generous sharing of time and talent by all members of the crew. "There always seems to be a new excitement with the start of each new season that keeps all of us coming back for more."

He has a great love and passion for the MMB, videography, and video editing and is grateful to be able to give back to an organization that meant so much to him as an undergraduate student at Michigan.

Sarah Hanchar - Videographer / Photographer

Sarah joined the video crew in 2009 after marching Piccolo in the band from 2004 through 2007. Now living in Milwaukee, WI after graduation from the Ross School of Business, the draw of the MMB and Michigan Football on a crisp Saturday morning is what brings her back throughout the season. When not working audio, cheering on the team, or wishing there was a better twitter client for webOS (follow us on twitter @mmbphotovideo) you'll most likely find her behind her camera capturing the excitement that is a Football Saturday! Go Blue!

Chris Sorensen - Videographer / Photographer

Chris has been a member of the video crew since 2005. An avid amateur video producer and self-proclaimed marching band geek, he is a 3rd generation M football season ticket holder and hasn’t missed a home game in 20 years. When he was introduced to video crew through a friend, a lifelong dream was realized. Though never a member of the MMB, he is an enduring musician, marching with a saxophone throughout high school, and studying piano at the college level. He currently plays saxophone and percussion in the Downriver Community Band. Chris resides in Southgate with his wife Michelle and awesome kids Baker, and Veronica.



Jeff Stokes - Videographer / Photographer

Jeff has been with the MMB continuously since the fall of 1986. He marched in the trombone section for two years, one as rank leader, before being elected to Drum Major for the 1988 and 1989 seasons. Following his marching years, Jeff served as a graduate assistant for two years and has served as a member of the video crew since life required him to get a “real” job as an engineer in the auto industry. Jeff lives in Milan, Michigan with his wife, Teresa (a former MMB tuba rank leader), daughters Samantha and Jacquelyn, and about twenty dairy goats.



Jeff Wohl - Videographer

Jeff marched alto saxophone from 1981 through 1985 and then sat in the stands for two years after that. Realizing that he could not stand being just an observer (too much Yuba in him), in the summer of 1988 he asked director Eric Becher if he could volunteer for something MMB. Eric said his current video crew of two was leaving for real employment and that he should give videography a try -- best 'take the plunge' decision Jeff ever made. Jeff lives in Canton with his part-time videographer wife Terri and two die-hard teenage marching band children Benjamin and Sarah.
