Professional Summary

As a senior vice president with Colliers International, I specialize in the sale and leasing of industrial, office, land and R&D properties, with extensive experience representing corporate and institutional clients, locally and nationally. Comprehensive services include landlord, tenant and investor representation, corporate services, business development and project management.

I partner with Bonnie Halley, senior vice president; and Melissa Marks, senior associate, to serve clients across the West Valley submarkets of metropolitan Phoenix.

As an industry veteran with more than 35 years of commercial real estate experience, there are few situations I haven’t encountered. Most importantly, I acknowledge what I do not know and defer to other experts, when necessary. I am committed to placing the interests of my clients first, helping them understand what is required of both them and myself, while creating a smooth path to successful transactions.

Having previously served in the role of designated broker, I have a strong commitment to integrity and honesty in all aspects of my work and relationships. Clients and colleagues alike describe me as knowledgeable, conscientious, helpful and easy to work.

Before joining Colliers, I served as senior vice president of leasing with Phoenix West Commercial in Avondale, successfully establishing the firm as an industry leader in the West Valley. Previously, I held positions as senior vice president for Cornish & Carey Newmark and also senior vice president and designated broker for Trammell Crow Company in San Francisco, with responsibility for developing transaction opportunities for institutional and corporate clients at both firms. I also served as national real estate portfolio manager for the McKesson Corporation. Prior to that, I was a senior vice president with Jones Lang LaSalle.
