What Our Clients Say
I used William Dean as a probate attorney in a family trust case He wasn't able to resolve my issue through no fault of his own However he was incredibly kind, thoughtful and willing to take the case When it became apparent my case was not going to work out, he returned soos of my retainer without being asked Family, friends all said I threw my money away, but William Dean came through for me with his integrity
Robbi Sera
Mr. Dean and his associates handled my case with ease. il was a neighbor dispute and may have seemed a minor issue to other law firms, but Ohana Law was fair and balanced in their assessment of possible assistance William proceeded to outline the procedure, the cost, and the possible outcomes. Very good communication land he will actually call on a Saturday!) wholeheartedly recommend Ohana Law Firm!
Robby
William Dean is an honest straightforward trustworthy attorney and without him and his team I would have not been able to secure the custody of my children. Right from the start/was ensured by Mr.Dean that legally everything would work in my favor I just followed his instructions and let him cover the details so I didn't have to constantly stress about the case. This has been a very difficult and exhausting process and without Mr.Dean it would have been unbearable. I am so thankful! Another father gets reunited with his kids, it doesnt get any better!

Vahid Safavi
Positive Professionalism. Quality. Responsiveness Value We asked Mr. William Dean to help us with evaluating a real estate purchase This was a nice experience. Wiitiam is a smart and knowledgeable lawyer. Many other attorneys I had worked with in the past, let their education and experience get in the way of communicating with their cient William is among the few that standout in being good listeners and efficient communicators He listened carefully, identified our concems and categorized them in degree of relevance and importance. He then researched the facts efficiently and collected a full picture that was missing in the 3rd party's litte report. His help was essential for making our final decision with confidence I highly recommend him
