Regardless of account size, Callowhill Group partners with each client to understand business objectives, identify target audiences, and develop a holistic strategy that will yield results. Our attitude and approach - every client is equal, and we're not successful unless our clients have achieved success.

But, you don't have to take our word for it - instead, we let our partners speak for us:

Bloomberg Newsletter Group

“I have worked with Callowhill Group for several years now. As a busy newsletter publisher with over 34 million editions published each year, we require our partners to have quick turnarounds, be thorough and provide work of the highest quality, akin to the Bloomberg brand for which they are representing. I've continued to be impressed by their dedication, quality of service and overall professionalism in helping us achieve our strategic marketing goals. From providing excellent overall strategy documents down to overseeing the nitty-gritty of email testing and telemarketing scripts, Callowhill Group provided a fantastic level of service and I would not hesitate to recommend them for any marketing project.”

Nick Ferris - Global Business Manager
Bloomberg Newsletter Group

“Callowhill Group has been very instrumental in the growth of our business over the internet. Not only did they design and develop our websites and digital/social marketing programs, their ongoing management and insight have helped us to become a leader in our industry.”

Stuart Perlman - Principal/Co-Founder


Peninsula Publishing

“Callowhill Group played a critical role during the start-up of our company and the launch of Plastics Machinery Magazine. The team successfully managed all aspects of our circulation management and audience development efforts, including vendor identification, database design, audience marketing and postal compliance. Their strategic assessment of our needs and successful execution of our plan delivered the results we needed to establish a quality audience for our advertisers. We would not have enjoyed a successful first year of publishing without their support.”

J.A. Lewellen - President

“Callowhill Group is a great, professional company to work with. They are marketing experts that provide guidance through detailed marketing strategies, as well as the collateral to support the initiatives. Their attention to detail makes them an asset to any company.”
