Our Attorneys

Angela Petrusha established PETRUSHA LAW in 2015 with the vision of providing compassionate and accessible estate planning services to her community. Angela’s multifaceted background enriches her understanding of her clients’ concerns.

As a parent, spouse, adult child of a blended family, and diverse business owner, she is acutely aware of the challenges many face when making decisions about an unpredictable future. Her personal experience with the terminal illness and subsequent loss of a loved one—who did not have an estate plan—underscored the stress and disorder such situations can bring. This journey has inspired her commitment to thoughtfully assist others in navigating the estate planning process.

A lifelong resident of Humboldt County, Angela has established strong connections within her community. Her mission is to demystify the estate planning process, empowering clients to achieve peace of mind knowing their affairs are in order.



Angela’s personal interests include spending quality time with family and friends, trail running, reading, and weekends at Ruth Lake.
