Since 2007, Mr. Garcia-Strickland was the Laboratory Director and Technical Director of Eurofins Frontier Global Sciences and worked on several laboratory improvement projects including implementation of Eurofins Frontier Global Sciences first laboratory information system, capacity planning and analysis, LEAN initiatives, workflow optimization, reducing operational expenses, cost of goods sold analysis, and staff motivation and training.  All of these projects have sought to provide the clients of EFGS with the highest quality, more timely, and more competitive priced specialty analytical services.

Mr. Strickland has worked directly on several high profile, large volume projects in order to ensure that the customers of EFGS achieve their project objectives goals. He also oversees many of Eurofins Frontier Global Sciences method development tasks associated with the creation of new sampling and analytical techniques.  With experience in sample collection, field investigations, sample preparation, sample analyses, project management, data interpretation, and environmental regulations, Mr. Garcia-Strickland is well versed in trace metals and metals speciation chemistry and client requirements and expectations.

Dr. William Anderson has 35 years of experience in the environmental testing industry.

Dr. Anderson's particular expertise is in analytical methodology and supporting quality assurance programs related to trial burn programs. He has extensive project experience regarding the analytical program design of incinerator and ambient air permitting activities. As an analytical chemist, he directly participates in the design and implementation of new analytical methods developments, project specific testing, and supporting quality assurance protocols. Much of the work produced by Dr. Anderson and his staff is used to generate legally defensible performance demonstration test reports that are to be judged by various regulatory agencies, including the EPA and state authorities.

Dr. Anderson earned his Ph.D. degree in Analytical Chemistry at the University of Tennessee.
