Executive Profiles

Amin Irving – Founder, President and CEO

Mr. Irving is the President and CEO of Ginosko Development Company and is responsible for the overall performance and operation of all divisions of the GDC family of companies. Amin oversees the selection of various locations, the preliminary feasibility analyses, the purchase negotiation of projects, landscaping and architectural design, municipality processing and debt and equity financing.

Amin is driven to help catalyze vibrant, socio-economically diverse neighborhoods through housing development. He attributes his passion, in part, to his experiences while growing up as an only child in the Midwest. He became homeless at 9 years old while his mother transitioned between jobs and lived in a run-down motel for a while. As Amin recalls, “The amount of struggle we dealt with just to pay the rent brought serious pressure to not only my mother, but myself. Knowing that I am helping to alleviate that kind of pain, not only in the parent, but also in the child is what motivates me.” He was attracted to real estate development at 18 after his mother’s passing when he found himself in difficult negotiations over the sale of his mother’s home. “The broker thought that I should sell the house for $20,000 less than what I thought it could be sold for; and the house ended up being sold at my suggested price within two weeks. That sparked my real estate drive.”

Amin graduated from the University of Michigan Ross School of Business in Ann Arbor majoring in Finance and Real Estate. He was the recipient of the University of Michigan Achievement Award.

His previous work experience includes Investment Banking in New York City, where he has gained wisdom in effectively and efficiently operating development projects. In Citigroup’s Real Estate Equity Division, Amin conducted various financial analyses for Sale-Leaseback and Synthetic-Lease deals valued over $450 million. Some notable deals include Huntington Bank and Samsung properties.

However, in New York Amin realized that money didn’t buy him happiness and moved back to Michigan where he became an Analyst responsible for turning data into information while working for a Medicaid HMO.  He single-handedly found $4 Million in annual savings for a company on the brink of insolvency.

Mr. Irving has served on numerous Boards and Advisory Councils including the Chairman of the Board for both the Michigan Housing Council and the Area Agency on Aging 1-B.  Mr. Irving was awarded the prestigious Crain’s Detroit Business Top 40 Business Person’s under 40 years old.

Amin is the proud husband of Tiffaney Irving and a proud father of four children.
