"I have known Sean professionally for nearly 20 years. IMO he is probably the best cross-examiner in Orange County. Whether civil or criminal his preparation is always top notch and his questioning tenacious. If you have to go trial criminally or have a tough civil case where the defense is a well-funded corporation or government entity, Sean is definitely a lawyer you consider."

"I've known Sean for close to 10 years and witnessed his work both first hand and through word of mouth of trusted attorney colleagues. Based on this experience, I feel one hundred percent confident giving him the highest endorsement possible. In fact, I've received a few civil litigation referrals over the years from friends and family. These are important cases because they involve people I care about. Civil cases are beyond the scope of my expertise, and the one and only attorney that I trust to refer these cases to is Sean Hennessey. He is a tireless advocate for his clients. He always seems to have the right answer at his fingertips. Let me put it this way, if I personally needed an attorney, Sean Hennessey would be my guy."

"I have over 38 years of lawyering experience. Over a 15 year span, I’ve worked with, and observed Mr. Hennessey in numerous juvenile cases, and criminal cases, including reading transcripts of his trials. If any member of my family should ever need a lawyer in a criminal or juvenile setting, Mr. Hennessey would be my first choice for representation. His litigation instincts, particularly his cross-examination skills, are amongst the best in Orange County."
