About me

Every time I agree to represent someone, I take that case with the firm understanding that they are entrusting me with matters that can be life changing to them and I am greatly appreciative of the confidence they have in me.   I strive to give each client's case the personal attention it deserves and understand that it takes hard work and dedication to achieve the best results. 



I offer my clients someone with unique knowledge and experience necessary to successfully handle their case.   As a former Police Officer and Assistant Criminal District Attorney, I have gained valuable knowledge and insight that I utilize to my clients advantage. I have the experience in the courtroom as well as real life experiences that benefit my clients. 


I have represented clients in criminal matters ranging from simple traffic tickets to serious state felonies and federal crimes.  I have also successfully represented clients in civil matters such as divorce, child custody and personal injury cases such as car accidents and other forms of cases involving the negligence of others. 


I take pride in my work and believe that knowledge is only part of the equation.  I truly believe in the saying that hard work beats talent when talent does not work hard.  I will continue to work hard utilizing my education, training, courtroom and life experiences to sucessfully defend your case.
