Project Management Team

Steve & Jeff Crook will work with you throughout the entirety of your campaign.

Jeff Crook began working with Crook & Associates in 1994 as a caller. As the business grew, his efforts moved towards database research and management, where he continues to play a large role. Jeff became Vice President of Operations in 1999. He has and continues to work in every facet of Crook & Associates, giving him a unique perspective into what drives the success of our lead generation campaigns. Jeff works closely with our calling and database team to ensure we deliver the highest level of quality to our clients. 



Our callers are so superior to typical telemarketers that we don't call our services telemarketing, we call it Teleintelligence. Through our extensive training, our callers have achieved the highest level of expertise utilizing a communication skill set that facilitates reaching key contacts in a variety of industries.

All members of our TeleIntelligence staff work out of our location. This is done so that we can constantly monitor the quality of conversations taking place on behalf of our clients.

We have very low turnover. Our callers will stick with your account and familiarize themselves with your company. You will not be getting the "caller of the day." This allows us to discuss the progress of each client with our staff on a regular basis.
