He is happy as a clam to take your money, but does not comply with professional standards for his professional nor abide by attorney-client privilege. I would avoid releasing any personal details to him (home address, etc.) which would preclude further contractual agreements. Unfortunately, there is so much cronyism amongst Contra costa attorneys to the point of complete disregard for clients.

I suggest avoiding a referral service such as the CCBA, and find either 1) a very seasoned attorney who is more careful your information or 2) a younger attorney who is more eager to earn your trust and future business.
