Biff began coaching baseball in 1977 with Gunbarrel Lefthand Valley Recreation Association, now known as Niwot
Youth Sports (NYS). After several years of coaching the 13-14 Pony Baseball teams for NYS, he turned to
coaching softball when Randi began playing. In 1986, his 12 & Under team took third place in the state in Class
“B” ASA softball. He later served as an assistant coach for the Boulder Flyers competitive teams until Randi went
on to pitch in college.
Biff returned to coaching baseball for NYS in 1988 when Michael began playing, and continued to coach his son’s
teams, including 12 & Under All-Stars and 13-14 Competitive Teams, through 1996. He also returned to coaching
softball when Katie began playing in 1995, and reestablished the competitive softball program for NYS, known as
the Niwot Thunder, in 1999.
Biff grew up in Creighton, Nebraska, where he played baseball from PeeWees through American Legion. His
favorite player was Ernie Banks, so Biff played shortstop and first base as a youth before becoming a catcher for
the first time as an 18-year old. In 1983, his wife Susan sent him to play with Ernie Banks and other members of
the 1969 Chicago Cubs as a participant in the first-ever Fantasy Baseball Camp in Scottsdale, Arizona.
After playing fast pitch and slow-pitch softball for many years, Biff returned to the baseball diamond in 2000,
playing for the Mudhens for four years in the 38+ Division of MSBL before a torn Achilles tendon ended his playing
career in 2003.
Biff has been a board member of Niwot Baseball, Inc., the summer baseball organization for Niwot High players,
since 1981 when it was founded by Coach Bob Bote. Biff also served as President of Niwot Youth Sports from
1983 through 1985 and from 1990 through 2000, and as NYS Baseball Director from 1987 through 1996.
In his other life, Biff is an attorney with Warren & Carlson, LLP, in Niwot, Colorado where he has practiced law
since 1975. He also serves as Managing Editor and Sports Editor for the Left Hand Valley Courier, a monthly
newspaper serving the Niwot-Gunbarrel-South Longmont area, which he helped found in 1997. He and Susan
have three grandchildren, Jordan and Jenna Willemsen. All of them are Cubs fans.
