Longtime Northern Colorado commercial real estate professional Don Marostica is retiring by the end of the year.

His partners, Nathan Klein and Blain Rappe, will be buying out Marostica's share of Loveland Commercial.

Marostica and business partner Eric Holsapple were equal partners in the company, but both have been increasingly involved in other ventures in recent years.

Because of those changes, Klein and Rappe have been increasingly involved with the day-to-day operations of the company.

Marostica served for 18 months as the executive director of the Colorado Office of Economic Development and International Trade, and Holsapple recently took a job as the executive director of the CSU Everitt Real Estate Center.

News of the changes was made public at Wednesday's Everitt Real Estate conference at the Marriott in Fort Collins.

Holsapple will remain the majority partner at the firm, Klein said.

The change has "been in the works for awhile," Klein said. He has been at the company since 2004, and became a partner in 2006.
