Michael jordan, CeO

Mike Jordan began his circulation career in 1991 with Petersen Publishing, publishers of Motor Trend, Hot Rod, and Teen, to name a few. First building a foundation of knowledge in renewals, bills, and circulation analysis, he eventually oversaw all subscription sales for 13 of Petersen’s 32 magazines at the time. In 1996, he left to become the Circulation Director at Los Angeles Business Journal.

There, he developed subscription promotion campaigns for the 20 year-old publication that caused circulation to grow by 30%. He also tripled circulation for the start-up San Fernando Valley Business Journal. Having experienced outside fulfillment with Petersen Publishing, and having run the in-house fulfillment operations at the Business Journal, Mike next ventured into the fulfillment business.

In March of 2003, Mike joined ESP Computer Services as the Director of Operations. In 2006, he became a part owner and shortly thereafter became the Chief Operations Officer. In that role he oversaw 50+ people comprising Account Executives, Customer Service, Administration, Lettershop and Sales.  In 2017 Mike was named ESP’s CEO.

Mike has served on the board of directors for the Western Fulfillment Management Association for 14 years and is a past WFMA President. He has served as the conference chair for CircDay LA three times, and for the Association of Area Business Publications three times. He has spoken at events for MCMA, WFMA, AABP, Folio:West, and the Los Angeles Direct Marketing Association.

Jack miller, chairman

Jack Miller graduated with bachelor’s degree in mathematics from the University of Washington in 1962. He served in the US Army for 8 years, including a one-year stint in Vietnam, attaining a rank of major in the signal corps.

In 1971 Jack joined ESP Computer Services, Inc. to help design system applications to handle appointment setting, scheduling, and billing in various industries.

ESP became the fulfillment company for Variety Magazine in 1981 and then began to focus solely on magazine fulfillment. As such, ESP’s system was designed from the outset as a real-time, fulfillment system suited for daily publications. Jack and ESP spent the better part of the 80’s programming a platform with great flexibility. Jack loves to develop programmatic solutions to the most complex problems, and Variety provided that challenge.

ESP emerged from the 80’s capable of handling mixed-circulation publications, daily frequencies, hand delivery, and high-end customer service. In the next decade, Jack and ESP started to reap the benefits of their programming expertise, as word of mouth spread and prospective clients began to call on ESP. New clients led to new problems to solve. With Jack’s leadership and foresight, ESP integrated a product system linked to the subscription system and offering a single-customer view. They also began to manage online access with usernames and passwords.

Today, ESP is on the cutting edge of technology with its integrated database, XML web services and intuitive client interface which offers great access and visibility into subscriber information, reporting and system procedures. ESP has grown in size and stature, but its philosophy is the same as Jack set forth so many years ago: "to provide customized solutions designed to meet each client’s unique business requirements." As a premiere, boutique, fulfillment company, ESP now has a staff of over 60 employees who handle over 250 publications.

Joe Hamby, Director of Technology

Joe Hamby started working for ESP in November of 1997 as a Warehouse and Distribution Clerk.  Being curious as to how all things worked, Joe was able to move around the Operations Department over the following years.  He served as Lettershop Operator, Production Operator, Operations Assistant Supervisor in spring of 2000 and finally as Operations Manager.  As the Operations Manager he was in charge of the Warehouse, Distribution, Lettershop and Production.  While in this role being in charge of Lettershop introduced him to some programming on Lettershop templates.  Soon after, he changed how Lettershop does its merge/purge by creating a generic Lettershop program that streamlined a lot of the processes and saved the clients money in Lettershop fees. By the summer of ’06 he starting updating Lettershop email templates and small web page changes officially moving him into the Programming Department under CTO, Stefan Beeli.

Over the next several years, Joe  kept learning and applying his new skills to ESP systems.  He has written several custom solutions to meet clients’ needs.  He's worked on everything from custom web pages and shopping carts to batch type programs and API integrations.  Even before becoming the Director of Technology, he took several co-workers under his wing and helped them go from Entry and Jr. Developers to Mid and Senior Developers.  Today, Joe, under the continuing tutelage of the CTO, has become ESP's go-to-guy...that employee who knows at least a little about everything, and can figure out whatever he doesn't yet know.

As the Director of Technology, he's assumed the responsibility of most technical aspects of the system on the PC side.  Joe adds value to ESP by working hard to search and implement any new features that benefit the company, and at the same time he trains and inspires his development team to contribute in that same way.
