Company Leadership

Over the last 15 years, Mr. Dalpee has nurtured a variety of technology-oriented business enterprises. His success eventually culminated in the business that served as the basis for the 1998 founding of ESI, where he is currently Vice President and Chief Technology Officer. Although Mr. Dalpee has held numerous positions of significant responsibility in large corporations, he felt such enterprises often failed to recognize and reward the contributions of all employees in creating a successful enterprise. Mr. Dalpee brought this vision to the founding of ESI, which is embodied by the motto he coined, "Our people make the difference."

Mr. Dalpee's long career in the industry began as a software engineer after graduating with a BSEE from the University of Maryland in 1976. He earned a MSCS from the University of Maryland in 1982, and in 1980, Mr. Dalpee began his intelligence community career as a contractor, where he led software development activities. As a result of this experience, he invented a distributed software communication model, described in a 1993 IEEE Parallel & Distributed Technology article entitled "Beyond RPC: The Virtual Network." In 1995, Mr. Dalpee was a key reviewer and contributor to Grady Booch's seminal object-oriented development book, Object Solutions.

Ms. Zadjura joined the ESI team in 2003. Reporting directly to the President, Ms. Zadjura manages the daily operations of all ESI contracts. Ms. Zadjura prides herself on understanding each program's contractual and technical requirements, ESI processes and procedures, the customer, and the career objectives of the technical staff. She focuses on employee and contract performance as the key to success so that ESI can provide the highest quality customer service.

Ms. Zadjura has spent over 30 years in the Federal government and industry serving the Department of Defense (DoD) Intelligence Community as a Software Engineer, Project Manager, and Program Director. In 1978, Ms. Zadjura graduated from Loyola College in Baltimore with a BA in Mathematics and began her career as a computer science professional with the DoD, where she held several positions of technical leadership in software and networking programs. After departing Federal government service, Ms. Zadjura received a Masters of Engineering Science degree in Computer Science from Loyola College in 1985. For the past 25 years, she has continued to support the intelligence community as a Software Engineer and Program Manager. Ms. Zadjura is certified as a Project Management Institute Project Management Professional (PMP).

Subsequently, he was appointed as Director, Enterprise & Mission Systems Programs in February 2008. In this position Mr. Hoyle continues his dedication to enhancing ESI's outstanding reputation for customer and staff satisfaction.

Mr. Hoyle graduated from American University with a Master's degree in Computer Science in 1978. He immediately began Federal service in the Intelligence Community as an Associate Computer Scientist, and completed his tenure as a Work Center Chief in 1986 when he entered private industry. Prior to ESI, Mr. Hoyle supported Intelligence Community initiatives as a software engineer, systems analyst, software, project and program manager, operations manager, and strategic business director. Mr. Hoyle was certified as a Project Management Professional by the Project Management Institute in September 2006.
