What Our Clients are Saying

“Chad at Quantum was able to close a very complicated transaction for our firm. He found a buyer who paid retail pricing and closed prior to our completion. This took skilled brokerage and great facilitation. I have known Chad for over 15 years and I would recommend him to others.”

Jason Smith, Smith Capital Management

“Working with Dan Waszak was an excellent experience. Throughout the transaction process, Dan was there to help facilitate, overcome challenges and ensure a smooth closing. I would highly recommend working with Quantum and plan to do so again in the future.”

Chu Ho Son, Property Owner

“Zack Hilgendorf is a seasoned professional specializing in investment sales across the country. We continue to recommend Zack to our clients on any disposition for retail product in Chicagoland Area and look forward to a continuation of this profitable working relationship.”
