Mr. Dare joined Geosphere in 2012 and has over 30 years of professional experience as a geotechnical engineer in the San Francisco Bay Area and Northern California. With a Masters in Engineering from UC Berkeley and over 15 years of specialty experience in geotechnical construction and materials testing, he has served as a construction and materials testing group manager at various companies.  Mr. Dare specializes in the local and regional geotechnical practice, and has served local and regional government clients such as cities and counties as well as transportation, water and wastewater agencies; educational and healthcare institutions; industrial clients, and commercial and residential developers. He has extensive experience managing projects involving California Division of State Architect (DSA) or Office of Statewide Health Planning and Development (OSHPD) oversight.  His engineering expertise includes site investigations, shallow and deep foundations, settlement and slope stability evaluation, retaining wall design, soil improvement methods, and pavement design.  Mr. Dare has also served as a geotechnical peer reviewer for a number of Northern California cities and counties.

Ms. Jackson joined Geosphere in 2017 and has been providing geotechnical engineering services in the San Francisco Bay Area for over 30 years. With a Bachelor’s degree from Harvard University in Geologic Science and a Master’s degree in Geotechnical Engineering from UC Berkeley, her background in geology, earth science, and geotechnical engineering provide a relatively unique combination of study that facilitates recognition of the relationships between subsurface materials and their engineering characteristics. Ms. Jackson has been responsible for business development and management of geotechnical engineering services including completion of geotechnical investigations, soil sampling and laboratory analyses, engineering analyses, preparation of geotechnical recommendations and design criteria, report preparation, plan review, construction observation and testing services, and expert witness services as well as other geotechnical engineering related consultation. She has provide geotechnical engineering consultation for a wide variety of projects including schools, medical facilities, fire stations, commercial construction, retail facilities, mixed-use developments, and residential structures. Ms. Jackson has experience performing engineering analyses for design of both deep and shallow foundations systems, restrained and un-restrained retaining walls, underground utilities and structures, flexible pavement, reinforced earth embankments, static and dynamic settlement, bearing capacity, resistance to lateral loads, lateral earth pressures, static and pseudo-static slope stability, liquefaction evaluation, post-tensioned slab, and effects of surcharge loads. Ms. Jackson has worked on projects which included complex slope stability issues involving existing residences on actively moving landslides, shoreline and levee stability, and emergency landslide repair.

Dr. Shrestha joined Geosphere in 2011 and brings with him over 12 years of experience in civil engineering and over 6 years of geotechnical engineering projects conducting analyses, design, and providing recommendations to the simple and complex problems.  He has extensive research knowledge and experience in recycled asphalt pavement (RAP). Dr. Shrestha has extensive knowledge and experience in Superior Performing Asphalt Pavements (SUPERPAVE) and Mechanistic Pavement Design methods. His engineering expertise includes pavement management, Pavement design, asphalt mix characterization, site investigations, shallow and deep foundations design, soil mechanics, slope stability and settlement analyses, geo-synthetics, design, MSE walls and retaining wall design, and soil improvement methods. Dr. Shrestha has experience managing projects involving California Division of State Architect (DSA) or Office of Statewide Health Planning and Development (OSHPD) oversight. He has excellent knowledge in seismic hazard, settlement, and liquefaction analyses. He has excellent knowledge in the application of finite element analysis to provide solutions to stability, support and dynamic problems in geotechnical engineering.

Ms. Salas joined Geosphere Consultants in 2016. Before joining Geosphere, Ms. Salas was a marketing and corporate communications consultant for various AEC firms in the Bay Area. She brings over 15 years of experience and proven track record of successful marketing and corporate communications campaigns. Ms. Salas is an active member of SMPS and volunteers her time providing marketing and graphic design services for local community groups.

Mr. Garcia has been a staff engineer at Geosphere Consultants since May of 2011 and works to support the geotechnical group. His experience includes nuclear gauge testing, concrete sampling, construction observations, and assisting with engineering investigations. Jose is the group lead for graphics and computer aided drafting.

Mr. Anastasio joined the Geosphere team in May of 2014. As a graduate of Cal Poly, San Luis Obispo’s Civil Engineering program with a focus in Geotechnical Engineering, he uses his knowledge gained in the classroom as well as the field to assist the team with site investigations, project analysis, and drafting. He is currently an Engineer-In-Training, and is working towards becoming a Professional Engineer. So far, he has experience providing construction observation for footings, pile driving, and drilled piers, in addition to performing nuclear-gauge compaction testing and coordinating analytical testing of soil.

Mr. Lim joined Geosphere Consultants in 2015 and graduated from Cal Poly, San Luis Obispo with a Masters in Civil Engineering with a Geotechnical Engineering specialization. Mr. Lim’s experience nuclear gauge testing, concrete sampling, construction observations, assisting with geotechnical engineering investigations, and performing analytical testing of soil and water.
