About Klosek Law Offices

Estate Planning, Probate and Trust Attorneys in Northern California

About us | Our Mission

At Klosek Law Offices, our mission is for our clients to walk out of our offices feeling secure and with the peace of mind that they are leaving not their just assets, but also their legacy and values to their children and other family members.

We aim to develop long lasting relationships so that you can count on us now and in the future.

When you retain our firm, you will not get relegated to a paralegal and paralegals never draft any legal documents. You will always work with an attorney in our firm because in law as in life, experience and qualifications matter.

Jack Klosek

Attorney

A Bay Area Native, Jack grew up in Mountain View, California, before moving to Berkeley to attend UC Berkeley (go Bears!). Jack always wanted to practice law and be close to family and friends, so he decided to go to UC Davis School of Law.

After finishing law school, Jack worked at the Santa Clara County Courthouse, assisting probate examiners with probate matters and acting as the research attorney for the probate department judge.

Jack then transitioned into private practice working at several high-end boutique estate planning firms, including Watson & Machado LLP, WealthPLAN, PC, and GVM Law LLP, where he honed his skills in probate administration, trust administration, and estate planning.

My favorite part of estate planning is getting to know people from all walks of life, understanding their needs, and working with them to best accomplish their goals.

When not serving clients, Jack enjoys spending time with his family, playing pick-up basketball, training his beautiful German Shepherd named Nala, and wine tasting in the surrounding areas.
