HGL made this process easy!

I finally took the time to create my trust and working with Hiraizumi Law Group was a no-brainer. Jill made the process easy, understandable, and I felt supported every step of the way. Estate planning can feel overwhelming, but she broke everything down clearly and answered all of my questions with ...patience and professionalism. I truly appreciated how organized and efficient the entire process was. I left feeling confident that everything was set up properly and that my wishes were clearly documented. If you’re looking to create a trust and want someone knowledgeable, thorough, and easy to work with, I highly recommend Hiraizumi Law Group. It was such a positive experience from start to finish.

Overall Great Experience

Jill and her staff were extremely helpful. They walked us through all the steps and took time to understand our situation. I would recommend Jill to anyone who is looking to help their senior family members make an estate.

EXEMPLARY ESTATE PLANNING

I recently met and hired Jill and her law firm to handle my estate planning needs/documents when my previous attorney retired. Jill reviewed all of my in-place docs (living trust, will, advance medical directive, durable power of attorney, etc.) to make sure they were up-to-date, both with current l...aw but most importantly, met my specified beneficiary desires across these docs. She identified some specific adjustments and enhancements that she believed would further strengthen legally on how/what I wanted my estate to be administered when that time comes. I found her insights and recommendations to be on-point and frankly, helped me to deepen my understanding of legal language as it relates to what she understood were my intent(s) and desires. In addition, she is extremely personable and attentive - which helped to develop an instant rapport - and most importantly, trust in her suggested enhancements and revisions. I am very pleased to have Jill as my estate planning attorney!
