The following is from Len's profile at wtmj.com:

Len used to dig into his favorite sports stories on the Wisconsin Morning News. Len's radio career began while still in high school as a sports anchor on WMMI in his home state of Michigan. After graduating from Marquette University, he worked at WISN for a year-and-a-half before bringing his talents to WTMJ.
Here's Len with his former co-horts on the Green House radio show!
