Professional Summary

Brian Gleason, SIOR, is a senior vice president with Colliers, specializing 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.

Brian partners with Bonnie Halley, senior vice president; Melissa Marks, senior associate; and Danny Schuster, associate, to serve clients across the West Valley region of metropolitan Phoenix.

As an industry veteran with more than 35 years of commercial real estate experience, there are few situations Brian hasn’t encountered. Most importantly, he acknowledges what he does not know and defers to other experts, when necessary. He is committed to placing the interests of his clients first, helping them understand what is required of both them and himself, while creating a smooth path to successful transactions.

Having previously served in the role of designated broker, Brian has a strong commitment to integrity and honesty in all aspects of his work and relationships. Clients and colleagues alike describe him as knowledgeable, conscientious, helpful and easy to work with.

Before joining Colliers, Brian served as vice president of leasing with Phoenix West Commercial in Goodyear, successfully establishing the firm as an industry leader in the West Valley.

Previously, Brian 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. He also served as national real estate portfolio manager for the McKesson Corporation. Prior to that, Brian was a senior vice president with Jones Lang LaSalle.
