  • Kenneth Francis Matejka

    As a Bay Area entrepreneur and business owner who has had numerous conversations with David, I have complete confidence in his business acumen and knowledge of the law. Through my 17 years as a staff attorney at the Bar Association of San Francisco, I came in contact with scores of business attorneys and David is certainly at the top of my short list of attorneys I would contact should a business legal need arise, or should someone approach me for a referral.

    I've known David professionally for nearly 20 years, and strongly recommend him for entrepreneurs, companies, and investors. Technically, David is among the strongest lawyers I've ever worked with or encountered opposite transactions; but what makes him an extraordinary counselor is the care he takes to understand his client's business goals and then deliver legal service that really helps achieve those goals. I'd be delighted to speak directly about my experience with David.
