After completing his military service Larry graduated from the University of Alabama in Birmingham. He worked repairing and installing pumps while designing his own products at night. For a period of time, Larry ran his own pump rebuild shop. He began incorporating some of his original ideas to improve the service life of the pumps. This delighted his customers.

Larry incorporated his own company in 1988 after developing a tool that broke the code on identification of rubber compounds used in o-rings and other seals and gaskets. Today this tool is the standard in the industry. It is exported all over the world and is used by hundreds of thousands of mechanics and technicians to avoid accidents and spills of liquids and gases. This tool is purchased and used by every major industrial pump, seal, hydraulic, pneumatic and instrumentation manufacturer in the world. It is also popular in aviation maintenance.

Larry has also developed an invention that resolves various operational problems and stresses in pump seals. Larry has inventions that are useful in other industries like surveying / civil engineering, farming equipment, and even household products. He is an active member of the American Society of Mechanical Engineers (ASME)

At first Larry lectured on how to correctly rebuild pumps and seals. Over the years the courses have taken another tack. Nowadays the lectures are dedicated toward how to STOP rebuilding pumps and seals by recognising maintenance, operational and design errors and identifying and eliminating the factors that lead to failure of process pumps. Larry has authored a book on pump theory, design and maintenance. The book is titled :Know and Understand Centrifugal Pumps" and is published by Elsevier Science. Larry published his own version of the book in Spanish.

Larry is known by thousands of industry professionals by his alter ego "The Pump Guy". Larry writes the popular Pump Guy column that appears in Energy Tech Magazine, World Pumps Magazine, and Flow Control Magazine and to some 40,000 monthly Internet subscribers. The Pump Guy has a running 'CHEAT SHEET' of useful pump information and hints that come from questions asked in his classes and experiences as a pump consultant.

Having functioned as an apprentice, mechanic, technician and even design engineer, Larry relates easily with the engineers, mechanics and equipment operators who attend his classes. Larry travels about half the year, some weeks teaching and other weeks as a pump consultant. When not traveling, Larry lives in Tennessee where he continues inventing new products. He has taught as adjunct faculty at Cumberland University and also at the Tennessee Technological Center. Larry speaks, reads and writes fluent English and Spanish and teaches his courses in both languages.
