What our Clients Say

Real testimonials from real business owners and executives.

 I have worked within the Brokerage Community since 1998; with Brokers and their Construction Managers. I have used the services of the major firms with 3 of the top firms in the industry. David, Kate, and Evan managed to exceed my past experiences and move past the history that had been created to broker and close my last lease. It was unexpected and unparalleled: I couldn't have been more satisfied with the result.

David B. Haley

Whitebox Real Estate provided our company with a flexible and dedicated approach on our headquarters office lease. They more than exceed our expectations.

Kate Clapper

CFO at CES Holdings

Thank you for the superb job and support you gave us in locating office space, deciding the best alternative, and negotiating the most favorable lease terms. We were under a very tight time schedule, and needed direction and a guide through the lease process as we found our first office. Additionally, we appreciate the creativeness Whitebox brought to the negotiations. Thank you for the great support. I would highly recommend your services to business owners, entrepreneurs, and startups alike.
