Timothy was born in the Netherlands, and his family immigrated to the United States when he was 6 years of age. He was one of five children and has four older siblings. His family settled in Walnut Creek, California, where he was raised and attended high school. He attended Diablo Valley College, in Pleasant Hill, and graduated from UC Berkeley with a B.A. in Political Science in 1982. He attended Golden Gate Law School and graduated with his J.D. in 1987. While attending law school, he met the woman that he ultimately married, and they have been together for thirty-six years. They have a son who is a police officer and a daughter who is a homemaker, and four grandchildren.

Timothy is licensed to practice in California and has been an active member of the California State Bar since 1987. He is admitted to practice before the United States Court of Appeals, Ninth Circuit, and the United States District Court for the Eastern, Northern and Southern Districts. He has a BV rating with Martindale-Hubbell. During his many years of practice since 1987, he has litigated and tried cases in both state and federal courts. During the course of his practice, he has tried an excess of thirty-five bench trials, almost all of them having resulted in favorable decisions. His practice consists exclusively of litigation since his admission to the bar. At present, it includes complex litigation, probate and trust litigation, fiduciary abuse, business and commercial disputes, professional negligence and landlord-tenant disputes.
