About Us


Howard Calderon
Howard CalderonCEO

Howard Calderon was born and raised in a family that had vending in its blood. Calderon Brothers Vending was the largest independent food service, snack, and beverage vending operator in the state of Indiana until his family sold the business in 2009. Howard grew up in the business by working every job within the company, from sweeping floors as a young man to eventually rising to the CEO position.

The entrepreneurial spirit in Howard was made evident when he and his three siblings founded IVM, Inc. in 1991. IVM was founded to manage the traditional vending operations of large clients that have multiple remote locations throughout the United States and Canada. This service allowed the Calderon family to extend their impact on the vending world beyond Indiana and into the international arena. In 1993, Howard devised the world’s firstautomated supply-vending solutions to control and monitor the distribution of various supply items to the employees of his clients.Those systems now operate in all 50 United States and 29 foreign countries. Howard continues to lead IVM through his strategic stewardship and direction.

Howard understands his success is based not only on his own efforts and abilities, but also on the IVM staff and exemplary client service that has become the hallmark of IVM. That unrelenting focus has created a loyal customer base that drives the continued success of IVM.
