The group bills itself as “North America’s largest thoroughbred horse-racing company.”
Dunbar said he withdrew his lobbying registration for the group on Friday. The parting was mutual, he added.
“I am eternally grateful to (Stronach Group founder) Frank Stronach for the opportunity he gave me and wish him nothing but the best,” Dunbar said in a phone interview.
Dunbar said he first started representing Stronach in 1999.
This summer, he is acting as executive vice president and general counsel to another client — Baha Mar, an integrated casino-resort in Nassau, Bahamas.
Dunbar will return this fall to the Jones Walker law firm in Tallahassee, where he remains a partner.
