Proof of OUr Results
“I’m someone that was been involved with Law Enforcement for over 25 years including a career with the NYPD as a front line supervisor as a Sergeant in the NYPD. I can tell you from firsthand experience, both personal and professional dealings with Mr. Seifer, he is a true professional in his field, however he has a great asset that is truly lacking out there lately, that is… “Honesty & Integrity”. If he promises you something he delivers! He is always prompt, courteous, and highly competent to handle any task he’s given. He can be trusted with the most sensitive of issues to the most routine.”
“I spoke with Matt the week after Thanksgiving about locating my car. While he wasn’t able to help, he was a kind voice of direction in a sea of rude and unhelpful local police officers. Months later he followed up with me to find out if the vehicle was ever located. Thankfully it was. I am thankful for the kindness and compassion showed.”
