Tamlyn Tills, the Forester women's golf team's head coach during the varsity program's first three seasons, enters her seventh year as the program's associate head coach in 2023-24. It will be her 13th year working with a varsity golf program at the collegiate level.

With Tills on staff, the Foresters have finished among the top teams in the league in nearly every year of the program's existence. After placing fifth at the Midwest Conference Championships as a first-year program in 2014, Lake Forest climbed a spot in the standings to fourth in 2015, moved up another place to third in 2016 and 2017, and was the runner-up in 2018. After changing leagues, Lake Forest has averaged a third-place finish in four St. Louis Intercollegiate Athletic Conference Championship Tournaments with a top placing of second in 2020-21.

The Foresters have had 14 all-conference performances in the program's first nine seasons with at least one player in the top five at the league championships in all but one year.

The Foresters have also been successful in the classroom with 23 SLIAC All-Academic or Academic All-MWC awards in program history.

Tills was the head women's golf coach at Loras College from 1999-2002. The Duhawks finished as high as third in the Iowa Intercollegiate Athletic Conference standings and in the top half of the league in each of Tills' three years as head coach. A pair of Loras players earned a combined three All-IIAC honors under her direction.

Upon joining the Forester staff as the head women's basketball coach in 2008, Tills also took over as the advisor and head coach of the golf team, which competed under club sport status until 2014. She has won 293 games as a collegiate basketball coach, including 157 with the Foresters.

Before coming the Lake Forest, Tills was the head women's basketball coach at Concordia University Chicago, Loras College, and Concordia University in St. Paul, Minnesota. She was also an NCAA Division I assistant coach at Marquette University and California State University-Fullerton and worked in the front office of the NBA’s Milwaukee Bucks.

Her coaching career began at Divine Savior Holy Angels High School in Milwaukee, Wisconsin, where she was the athletic director and volleyball and basketball coach.

Tills was also a successful collegiate athlete and is a member of the University of Wisconsin-La Crosse Hall of Fame.

She resides in nearby Libertyville.
