Our Mission: To provide customized vertical transportation services with a focus on customer satisfaction, timeliness and safety.

Professional Elevator Services, Inc. (PES), a certified MBE/DBE and bonded company, was incorporated in March, 1990 by Kenneth W. Mason. After earning an undergraduate degree in Engineering, Mason began working for a major elevator manufacturer. During this time, he saw an opportunity to provide more customized, reliable services to clients by starting his own elevator company. Launching PES while completing a master's degree in Engineering, his vision and dedication has resulted in PES becoming a trusted provider of elevator services.

PES brings together leading manufacturers of vertical transportation products and makes customized selections so that you gain the quality and purchasing advantages that result from our vast connections and expertise. PES furnishes and installs equipment from industry-leading manufacturers, whose equipment can be customized to fulfill your specific project requirements. Our suppliers comply with ANSI code and meet ISO 9000 standards. Beyond cost efficiencies, we provide a range of value to our customers; chief among them are the performance and reliability of our people. Our company is large enough to handle construction, modernization or maintenance projects, but small enough to give you the individual attention you deserve.

P.E.S. is an Equal Opportunity Employer. We have a strong track record for diversity. We employ those who are proficient in their trade regardless of race, color, religion, sex, sexual orientation, gender identity, national origin, veteran or disability status.
