Al Shacklett (Principal) is the founding principal of ORCA Consulting and has been a pioneer in the development and application of state-of-the-art analysis methodologies for the leisure industry over the past thirty years. His ongoing experience in project analysis has secured his position as a leading expert in the field of visitor capacity and circulation planning, contributing to the successful development of theme parks, national parks, museums, aquariums, zoos, science centers, visitor centers, fairs and expositions, sports stadiums and transportation systems worldwide.

After having served as a petty officer in the U.S. Navy and earning a bachelor’s degree in Mathematics and Master of Science degree in Industrial Engineering at the University of Florida, Al’s professional career began as the first industrial engineer at Walt Disney World to focus exclusively on the science of “Guestology” where he was involved with project development and optimization for theme parks, transportation systems and resorts for Disney resort developments in Florida and California. Al was the founding manager of the Theme Parks Industrial Engineering department at Walt Disney World, which involved management of a large staff of industrial engineers and working with Disney Imagineers and operations managers to improve the efficiency and productivity of the theme park, resort, and transportation facilities and operations. To support the growing worldwide Disney theme park developments, Al went on to establish the Industrial Engineering Project Development department, where he managed the work of a large department of Industrial Engineers and MBA’s and was integrally involved with the development of many major Disney projects, including Euro Disneyland, Tokyo Disneyland, and the Disneyland Resort in Anaheim. In 1993, Al recognized the opportunity to provide this type of project support to the general leisure industry and formed ORCA Consulting to enable the adaptation and refinement of analytical techniques originally created within the Disney “laboratory” to a wider variety of applications. Al’s support on projects includes sizing and layout recommendations to guide architects and designers as well as creative solutions to improve less-than-ideal spaces in existing facilities.

Al has been an invited speaker at many professional conferences, was nominated for outstanding achievement in Operations Research, was featured on ABC’s 20/20 program as an expert on theme park queues, and has taught classes in Engineering Economy, Operations Research, and Probability & Statistics as an adjunct professor at the University of Central Florida.

Zach Buran (Simulation Modeling Specialist) started working as a simulation specialist for ORCA in 2015, and possesses an extensive background in the operations research industry. He has a degree in Industrial Engineering from Georgia Tech, and since then, he has been consistently growing his career in operations research by learning over 5 different simulation software and applying them to many different industries such as pedestrian flow, traffic flow, and manufacturing. Zach has been an integral part in building simulations at ORCA that are able to assist in pinpointing areas for improvement in pedestrian flow environments, and his simulation scopes have ranged from aquariums, to national monuments, and everything in between. One of his biggest accomplishments at ORCA was creating a pedestrian flow simulation for the Yayoi Kusama Exhibition at the Hirshhorn Museum, where he programmed ORCA’s recommended timed ticketing system that the museum ended up using as a standard for the exhibition.
