John C. Sotter
Senior Technician John Sotter is a graduate of the University of California at San Diego in Urban Planning. His studies there included work in floor friction and in chemistry. He has 17 years of experience in responsible safety work for the City of San Clemente, California. He has trained in floor slip resistance testing in the U.S. and the U.K. (including pendulum and Tortus manufacturing facilities as well as chemical floor treatment projects) and does most of Sotter Engineering’s floor slip resistance testing work, both in our laboratory and from Hawaii to New Hampshire, British Columbia to Mexico, New York to Florida, and everywhere in between.
John’s 12 years of extensive experience with floor slip resistance testing using the BOT-3000E, British Pendulum DCOF Tester, Tortus digital tribometer, SlipAlert, and ASTM C1028 static friction, is unmatched in the United States. He has worked in floor friction testing and treatment in the USA, Canada, Mexico and on the high seas. His background includes many miles barefoot on wet surfaces: years of competitive swimming, international sailing, water polo (a high school All-American), and surf lifeguarding. John has traveled extensively in 24 nations.
