“Thank you for your wonderful work on the turn lane project on Highway 62 in 29 Palms. I appreciate the communication level you kept with the construction crew and myself, and the reports were clear and very well written. The crew was made aware of any and all desert tortoise concerns, the job was completed with no issues. I look forward to working with you again, thank you for your help.”

“David Lee provided biological monitoring services for PG&E on the Contra Costa-Las Positas 230 kV Reconductoring Project in 2009. He proved to be punctual, trustworthy, and quite knowledgeable of the sensitive species that had potential to be impacted by this project, includingCalifornia red-legged frog, California tiger salamander, golden eagle, Swainson's hawk, great-horned owl, burrowing owl, and San Joaquin kit fox. David conducted pre-construction surveys, prepared survey reports, and was very effective in communicating and implementing our protection measures with the construction crews.”​
