Expert's Profile

In 1989, I began working on roller coaster track systems, building them from blueprints, assembling the pipe rails, and welding the completed sections. Just over five years later, I founded AA Machining and Welding, Inc. After many years in this field, in 2000 I began working with zip lines and found my niche. Thereafter, I built zip line towers and passive braking trolleys, developed and tested trolleys and lines, and shortly found myself inventing better and safer braking systems. I have obtained three patents on my inventions. In 2009, I teamed up with city planners and professional engineers to design, build, provide employee training for and operate my own commercial zip line. Since then, I have become a member of multiple associations, including:

• A voting and committee member with the American Society for Testing and Materials (ASTM Committee F24 Amusement Rides and Devices) - An ASTM F24.61 AAC Task Group member F2959 Aerial Adventure Courses: ziplines, rope courses, aerial trekking, canopy tours, climbing walls, and (ASTM Committee F15 Consumer Products) for example juvenile products, toys, playground equipment and pool safety.

• A member of the Association for Challenge Course Technology (ANSI/ACCT).

• A member of the International Association of Amusement Parks and Attractions (IAAPA).
These affiliations has allowed me to acquire knowledge of over 300 ANSI, ASME, ACCT, PRCA and ASTM standards and procedures.

• A board member of the American National Standards Institute/Professional Ropes Course Association (ANSI/PRCA).
