Lucas M. Pastuszka

Associate Attorney
San Jose, California

Lucas M. Pastuszka is an attorney with Temmerman, Cilley & Kohlmann, LLP in San Jose, California, practicing in the areas of Estate Planning, Estate Administration, and Tax Law.

Lucas’ estate planning practice includes preparing revocable trusts, wills, durable powers of attorney, advance health care directives, and other estate planning related documents for clients. His trust and decedent's estate administration practice includes representing trustees, personal representatives, and beneficiaries in all aspects of trust administration. Lucas has personally drafted hundreds of estate plans and particularly enjoys meeting with clients, clarifying complex concepts, and being able to provide experienced advocacy to support his clients through an unfamiliar, sometimes overwhelming, process. He takes a personal interest in the success of his clients' projects and works with them to accomplish their goals.

Lucas earned his J.D. degree and Tax Concentration from the University of California, Hastings College of the Law, which makes him uniquely equipped to assist clients with complex estate planning tax issues and with estate administration. He also graduated with his bachelor’s degrees and honors from Santa Clara University, majoring in political science with a pre-law emphasis, psychology, and Spanish.

While still in law school, Lucas interned with the IRS Office of Chief Counsel, in the Small Business and Self-Employed Division, where he observed the innerworkings of the IRS and gained valuable tax compliance insight. He also witnessed the unfortunate consequences of poorly-crafted and non-existent estate plans, while interning at the Probate Department of the Superior Court of California in San Francisco. Having seen the impact on clients of poorly-crafted estate plans, Lucas offers estate planning services designed to accurately express clients wishes and minimize the risk of future disputes.

Lucas is a Bay Area native, of Polish descent, who enjoys volunteering in the community. He serves as Planning Commissioner for the City of Saratoga where he advises City Council on land use and urban planning matters.

When Lucas is not in the office, he enjoys spending his leisure time swimming, doing archery, ballroom dancing, water coloring, and volunteering at local hospitals entertaining children as Batman.
