I've worked with Commercial Progression regularly over the past 4 years (since 2011). Over that time, I've used a variety of their services. Commercial Progression delivers the intangibles that you can't always quantify or put on a line item.
Over the years we've thrown a variety of unique situations their way, and they've always been flexible, knowledgeable, and responsive to our needs. Those are the intangibles we've come to depend on. I would recommend them.
