Aerial Amusement Ride/Zipline expert witness. Bachelor of Science in Engineering, Machine Tooling degree, certified welder, three US Patents for zipline braking system and trolleys.

SUMMARY
• In 1989, I began working in the amusement ride industry, building rollercoaster track systems. I excelled in track manufacturing and design. Just over five years later, I founded a machining company. After many years in this field, in 2000, Park City Mountain Resort (PCMR) a ski resort in Utah, asked my company to design a passive braking zipline trolley and built large towers for the 2002 Olympics. In 2009, I teamed up with city planners and professional engineers to design, build, provide employee training, as an owner-operator of a commercial zipline. Since then, I have become an active member of multiple associations and committees, 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
• A voting and committee member 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)
• A board member of the American National Standards Institute/Professional Ropes Course Association (ANSI/PRCA)
• A member of National Association of Amusement Ride Safety Officials (NAARSO)
• Certified welder with American Society of Mechanical Engineers (ASME)

These affiliations have allowed me to acquire additional knowledge with over 300 standards and procedures, e.g. ANSI, ASME, ACCT, PRCA, ASME and ASTM.

As an Expert Witness, I have been retained in aerial adventure ride incidents and deaths. This has allowed me to provide evidence and testimony in multiple cases working with clients in Alaska, Arizona, California, Colorado, Connecticut, Florida, Georgia, Hawaii, Idaho, Nevada, Maryland, Minnesota, Missouri, Montana, New Mexico, New Jersey, New York, Oregon, Tennessee, Texas, Utah, Washington and Mazatlán, Mexico.
