What our founders are saying.

PSG and David helped us strategically re-think our 10+ vear-old business to future proof it. He added a business intelligence platform that allowed us to manage the company from an integrated modeling perspective. While here, he also helped motivate and re-engergize our teams with his positive and inspiring management style and exceptional communication and interpersonal skills. Would highly recommend him.

David/PSG helped us get ready for our institutional founding round and played a pivotal role in getting NuLife our first $3M Term Sheet offer from a VC firm. David’s majestic good looks made it a pleasure to get out of bed each day in hopes of another zoom call together. Without his rugged handsomeness and nurturing way not sure we would have made it.
