About me

Attorney Timothy Sullivan has a wide-range of practical experience in the defense of criminal cases.  His background includes a focus on the specialized and unique training law enforcement relies upon in making a DUI arrest.



Subsequent to graduating from law school, Tim was sworn in as a Pinellas County Assistant State Attorney. As a prosecutor, Tim learned street-level DUI enforcement tactics from the inside.  He quickly rose through the ranks in the State Attorney’s office and was selected to run the North County Traffic court division. Tim was promoted to “Lead Trial Assistant” and supervised other Assistant State Attorneys in their prosecution of DUI cases.


Tim has invaluable insight into the strategies often employed by both police officers and prosecutors. He completed the same specialized DUI education and training that law enforcement officers attend. Tim became certified to operate the Intoxilyzer 8000. However, his training did not end there.  He went on to achieve state inspector certification necessary to review the maintenance and calibration of breath testing machines before they can become legally employed by a police department to gather evidence in DUI cases.


Tim received a scholarship from the University of North Florida to attend the “DUI Drug Recognition Expert Program.” There, he studied alongside DUI Squad Officers in the complex area of Drug-Impaired Driver detection.


Tim’s focus and concentration in the area of DUI and criminal law did not go unnoticed in the legal community. Tim began training prosecutors at the Pinellas County Criminal Justice Center. Later, Tim was called upon to serve as an Adjunct Professor at Tallahassee Community College. In that capacity, he taught prosecutors from across the State on how to most effectively prosecute DUI cases.


As a DUI Defense attorney, Tim has handled hundreds of DUI offenses.  In this regard, Tim has successfully litigated Motions to Suppress his clients' breath and blood tests.  He has also successfully argued to have his client's field sobriety tests excluded from evidence.  Tim has also successfully sought acquittals for his clients in jury trials.
