As Principal Engineering Geologist at R.T. Frankian & Associates I am responsible for providing engineering geology and hydrogeology services to a variety of public and private sector clients. Projects include commercial/industrial/residential land development, geotechnical review services for municipalities, fault and landslide investigations, groundwater studies, seismic hazard studies, and many other projects. I have more than 20 years of professional experience in the applied earth sciences. I am a Registered Geologist, Certified Engineering Geologist, and Certified Hydrogeologist in California. I am licensed in two other states. I have broad technical and managerial experience.
As President, and Chief Executive Officer of Arroyo Geotechnical I was responsible for all aspects of start-up and development of the new company. Arroyo is a Wholly owned subsidiary of the Willdan Group of Companies and a spin-off of the Willdan Geotechnical Division which I started in January 1998. I reported to a five-man board of directors. I was responsible for building the company into a separate stand-alone entity with a 15-person staff and annual revenues around $2,000,000.
As Vice President at Willdan I was responsible for all activities associated with the development and start-up of the Geology/Geotechnical Division. I was responsible for providing geotechnical engineering, engineering geology, and hydrogeology services in support of 14 offices in California, Arizona, and Nevada. I was responsible for all division operations including profit and loss, marketing, preparing proposals, business development, staffing and training employees, assignment and supervision of work, assuring high quality work products, maintaining client relationships, collecting fees, and managing projects so acceptable profit levels were met. After Two years of building the division we split it off into a separate company called Arroyo Geotechnical of which I became President and CEO.
At Converse I had 11 years of experience in the applied disciplines of engineering geology, hydrogeology and geotechnical engineering in California, Nevada, and the east coast. I advanced from staff to Principal level in nine years. I managed infrastructure and development projects for public and private sector clients with total billings up to $1,500,000. I was responsible for project groups including up to ten engineers and geologists. My experience included marketing, cost proposals, scheduling, billing, and all aspects of field exploration, laboratory testing, and technical analyses. I lead innovative proposal presentations to a variety of clients. I became fluent in computer software for office and technical applications.
