"I can not thank Mike and Karen enough for their support, hard work, and diligence in our recent land closing in the Portland Metro. They were able to address our challenging demands and schedule adjustments with professionalism, flexibility, and precise execution to align the transaction with our expectations. I look forward to our next opportunity together!” Chris Kapper, Stack Infrastructure
"Negotiating commercial real estate deals is stressful stuff, fraught with complex concerns and costs. Through the pandemic, we were under duress as a company, we faced a new landlord, a lease renewal and were also looking for a subtenant to defray costs through the crisis. Karen and Mike immediately instilled a sense of calm with their expert knowledge. They confidently led us through all of it and I’m pleased to say we’re newly stabilized and happy with our lease and subtenant. Simply good people." Giles Rickett, Satis&fy
