Highly Recommend
Ian helped my sister and me with a "sticky" issue on our mother's trust that we thought was unresolvable. He explains things thoroughly and is very pleasant to work with. He makes you feel like he's a friend as well as your attorney.

Helpful and Insightful
Ian has helped my wife and me with our family trust. We have found him prompt, knowledgeable, insightful, and responsive to our needs. He is prompt in his communications. We have no hesitation in recommending him.

Very patient Attorney when explaining Estate Planning
Ian was very patient with my husband and I when reviewing the Estate Planning documents he prepared for us. It is a huge binder and a lot to review but he explained everything to us in terms we could understand and also each section has a page that also explains what you are about to read.

After my husband passed in June, I was not able to get a good night's sleep worrying about what would happen after my passing. I found HP Law was close to home, so I called. Thank God I did. I knew nothing about estate planning, but Ian explained everything to me in terms I could understand. The process was much quicker and easier than I had expected. Yes, I would highly recommend this practice.

Thoroughly impressed!
I am thoroughly impressed with the level of professionalism, time and detail HP Law dedicated to me when preparing my last will and testament. I literally knew nothing about estate planning, wills and how to properly plan for the "unexpected". Ian went above and beyond to make me feel comfortable and help me understand just how much my family will benefit from proper estate planning. I didn't realized that anyone can and everyone should have a will. Thank you Ian. Thank you HP Law.

Trust for 2
We are lifetime partners, who realized we needed to do something about are final arrangements. Having no idea which attorney to employ, I decided I would check around on the internet for one. Ian Hasegawa's name got my attention. I read several of the reviews former clients had written, and we decided to make an appointment. Well my curiousness paid off, for we received excellent advice and were very happy with our whole experience with HP LAW. Many thanks. GordieJoe

Probate Pro
Being out of state, it was surprisingly difficult to get timely legal help with probate following the unexpected passing of a loved one. The number of calls, the number of left voice mails and messages, the sheer difficulty of just getting a lawyer on the phone was frustrating. Mr. Hasegawa was immediately responsive, returning my requested contact the same day. He was professional in every sense of the word. He explained to me what needed to be done legally in understandable terms, executed a contract, and promptly started on the case. He did not over promise. He delivered needed documents well in advance of his estimated time frame and was reasonably priced. And I had the pleasure of dealing directly with Mr Hasegawa on most matters, as opposed to talking to a legal assistant. An excellent experience during what was otherwise a difficult time. Approachable, available, experienced.

Great Consult
I met with Ian about estate planning ideas, and he opened my eyes to the world of wealth and asset management and protection. He was extremely comfortable to talk to, and really down to earth. The way he expressed the intricate details about this area of law made it simple to understand and follow. I would recommend Mr. Hasegawa again and again.
