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.

Meet Jack Klosek


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.

Get to know Amber


Amber Hottes has been a licensed California attorney since 2005. Her experience has focused on estate planning – preparing Living Trusts, for both married and single clients, and irrevocable trusts for Medi-Cal planning.

Amber has lived all over the Sacramento region – she started off in Davis while attending law school at King Hall, then spent a few years each in Folsom, Oak Park, The Pocket, North Natomas, and Lincoln. She’s also been to what feels like every park with a field big enough to play a game of pickup ultimate frisbee (Curtis, Tahoe, and McKinley Parks are favorites).

Amber enjoys estate planning because it focuses on solving problems and helping her clients achieve peace of mind.
