"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

I would highly recommend Mike Thomas for a sale of this magnitude. Thank you, Mike, for your hard work." - Nathan Georges, CEO, Columbia Industries
