"The Rocks Biological team is smart, professional, and great to work with. I have enjoyed having them as a teaming partner on several projects in Southern California and would highly recommend them. "

"I first met Jim and the Rocks Biological team over 10 years ago on a project we did together on MCAS Miramar. His group really helped me navigate through tough biological requirements on the project and since that time we continue to use them on projects in the region. We consistently get great service from the Rocks team and we look forward to working with them for years to come.

"When we were looking to develop an integrated resources management plan for the Pala Reservation, Rocks Biological immediately responded with a comprehensive proposal that went above and beyond. Selecting Rocks to work with us on this big project was a great decision. They are professional, flexible, and skilled at developing a plan that meets the unique needs of a Tribal nation. I especially appreciate how they have helped me manage my priorities on this project, with patience and gentle nudging when necessary! The entire team is a pleasure to work with and I expect to continue a long and fruitful partnership with Rocks."

"... I am very grateful for the professionalism and flexibility that Rocks consistently provides to meet [project] needs and to keep projects moving smoothly. Despite being a smaller firm, the Rocks team also provides a prime-level expertise in a variety of key environmental areas. This allows our City of San Diego projects to receive top-level service and support while also opening up more opportunities to meet contract SLBE participation requirements, which can be challenging on contracts that shift priorities often. Lastly, a huge benefit of partnering with Rocks has been that they are just a fun group to work with and they mirror the main goal we have at our own firm: always taking their work seriously, but not themselves.”
