Testimonials
Steve Berghoff at Menlo Group listed our office space in Gilbert for lease. Steve and his team found a good tenant within a week and went above and beyond helping us through the leasing process. They are insightful, very knowledgeable and enjoyable to work with. The listing fee is reasonable. I highly recommend and refer Menlo Group and Steve Berghoff to everyone I know. I will absolutely utilize their service in the future.
Stanley Nguyen
Great group to work with. I had purchased a commercial office condo 7 years ago, and sold it this year. They kept me up to date on everything that was happening and Tanner went above and beyond in researching potential buyers. Very, very pleased. I wish I had agents like him in other states.
