Co-Owner – Tony Castaldi

Tony Castaldi is a co-owner of Great Lakes Seminars. Tony’s responsibility is ensuring that everything other than the actual teaching portion of our courses is top notch and evolving to meet the needs of our registrants.  

His way of doing this is staying out of the way of the Great Lakes Seminars’ talented staff and trying to help guide without limiting their ideas or skills. Although he is ultimately responsible for the non-teaching side of our business, he realizes that GLS staff members are in touch with our registrants and are therefore the best suited to address their needs.

Contrary to the popular belief that Tony enjoys romance movies, pastel colors and kittens, he actually loves simply doing anything with his wife and two boys, fishing, music and reading.
