Posted by Dennis | March 18, 2026 | Hired Attorney | Speeding & Traffic Ticket

Damon is amazing!

To say the end of '25 was horrible is certainly an understatement. I ended up getting pulled over and cited for speeding and cited for failure to yield near a stationary emergency vehicle all within a month. I drive a commercial vehicle for a living and leaving marks on my driving record is a no-no. ...I thought I was toast but I remembered Damon helped me out years ago for an incident where the end result was my driving record wasn't changed and I got all charges dismissed. I of course knew who to call with my latest problems and I am 100% satisfied with the results. He was able to make it so I didn't get any marks on my driving record for both incidents. I owe Damon so much. If you're in need for someone who will never give up and fight for you till the very end, then give Damon Petrehn a call. Thank so much Damon!

DUI Case

I highly recommend Damon for his services. I could write a novel about how terrific he was to work with in a long case (DUI) but most importantly the Results he achieved in the end. I would describe him as an Attorney who absolutely works to the end to achieve appropriate Justice for his Clients. He... left No Stone unturned in my case , he was simply Amazing! While I hope I never require services again, if I do , I'll call Damon in a New York second! He's the Best!

What determines Avvo Rating?
  • Experience & background Years licensed, work experience, education

  • Legal thought leadership Publications, speaking engagements
  • Discipline Disciplinary information may not be comprehensive, or updated. We recommend that you always check a lawyer's disciplinary status with their respective state bar association before hiring them.
