Professional Summary

As a senior executive vice president with Colliers International, I have been negotiating industrial real estate transactions in the Phoenix area since 1986. I specialize in the sale and lease of industrial facilities; land sales to users and developers; build-to-suit facilities for sale or lease; and the sale of single and multi-tenant industrial facilities (investment properties).

A native Arizonan, I have extensive local market knowledge. Having experienced many market fluctuations in my more than 30 years in the industry, I have a thorough understanding of current conditions and future trends. I recognize that timing is a key factor in real estate decision making and profitability.

I am committed to maintaining excellent relationships with both landlords and users. As a strong negotiator, I am focused on maximizing value for my clients and take pride in their success. Throughout my career, I have successfully negotiated more than 1,000 sale/lease transactions on behalf of my clients.
