About William
Biography
No matter what type of case I am handling, I pride myself on client communication. I file nothing on a client's behalf without giving the client an opportunity to review and understand each facet of every document. In court, I make sure the client is prepared to face the judge, and knows what to expect before each court appearance.
I also have extensivecourtroom experience. I have tried over 200 bench trials and 30 jury trials in my career. I am comfortable in any courtroom, whether it be a family law or criminal matter. I am not afraid to step into any courtroom and take a matter to trial/hearing to ensure that my clients receive favorable outcomes.

Reccomwndation for a great attorney!
I was issued 3 traffic violations. Most serious of the two were the accident and leaving the scene which the officer put me at fault. The day of court William Opal was fully prepared to fight my case. He had my case called first and total I spent about 15 mins in the court room and all charges agains...
William Lowell Opal's Lawyer Endorsements
"Bill is an excellent attorney in all regards. I do not know anyone more hardworking that Bill. What impresses me most about Bill is his compassion for his clients. I know Bill prides himself on communicating with his clients at all hours, even in the middle of the night if need be, so that they always feel comfortable and they always know what is going on. This is vital for individuals charged with crimes and also for those going through the difficult process of divorce. There are many attorneys out there who are primarily interested in making money off of their clients. Bill is not one of those attorneys, he genuinely cares about his clients and obtaining the best possible results for them. I would highly recommend Bill to anyone looking for a criminal defense or divorce attorney!"
"I have opposed Bill in divorce litigation. He is smart, thoughtful, and reasonable--a forceful advocate without unnecessarily incurring fees by exacerbating litigation where the cost/benefit does not warrant it."
"I have worked with Bill on several matters in the past. I have always found him to be a very knowledgeable and skilled advocate for his clients. I always enjoy working against Bill on resolving a family law issue."
"When I have an issue revolving around family matter I come to William Opal because I know he has likely experienced the issue I am having."
