“I have worked with Greg directly for all of our credit card processing and equipment needs going on 10 years.  I can give testimony to the fact that I have never felt the need to work with anyone else after working with Greg.  His commitment to our Event, our Company and to having cutting edge technology and service are above and beyond what you would expect! 

CGC Consulting is in a class all of its own.”


Michelle Simpson

“I’ve known Greg over 15 years and he has always been there for me while providing the best possible service. His professional approach and willingness to go above and beyond has made him a standout in the financial field. I would highly recommend Greg to anyone.”


Bill Frieder

“Since we’ve been doing business with Greg and GCG Consulting for almost two decades, we have had nothing but exceptional service. In fact, I tell merchant services telemarketers, we have a family member that handles this for us! Without a doubt, Preach Building Supply would highly recommend Greg and his staff.
