About me

My practice is dedicated exclusively to the defense of DWI and DUI charges. I am among approximately 50 attorneys in the state that are certified by Draeger on the Alcotest 7110, the instrument used to test breath samples for blood alcohol content (“BAC”). I have also been certified as an instructor in Standardized Field Sobriety Testing by the National Highway Traffic Safety Administration. These tests are used to establish both probable cause to arrest and driving while intoxicated (DWI) where there is no scientific evidence of blood alcohol content (e.g. Alcotest readings or blood sample readings). There are less than ten lawyers statewide that share this credential. I utilize my specialized training, as well as over thirty years experience defending and trying DWI cases, to secure favorable outcomes on behalf of my clients. Call me for a free initial consultation anytime 24/7 at 877-450-8301.

  • Travis J Tormey

    Colin is one of the best "technical" DWI defense attorneys in New Jersey. His knowledge of DWI practice and his discovery strategy inevitably wears down the prosecutor and gets great results for his clients. I highly recommend him.
