“Mr. Seifer provides a very professional, trustworthy service and is very knowledgeable in his field. He goes above and beyond to accommodate his clients to get the best results.”
Product Management Engineering – Max Mobilcom
“I will start with a conclusion – the job was done successfully! I have never dealt with private investigators, and i am glad i met a professional with a caliber of a person like Matthew – easy to deal with, comforting, professional, provided real solution and alternatives. My case was related to the divorce and all the investigation was legit and useful. Prompt, trustworthy, responsive, and importantly reliable. Thank you for your help!”
“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.”
New York State Regional Director at United Studios Of Self Defense
“I have worked for, and alongside Matthew Seifer for seven years and know him to be an intrepid investigator, who is thorough and professional. He has a broad range of experience and solid technical skills. Matt is ethical, conscientious and responsible in all matters of security matters and investigations.”
AHFI Fraud Investigator at Verisys Investigations Inc.
“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.”
“I have retained Radius Investigations to perform various investigative work. They always go above and beyond. I would recommend Radius to anyone or any entity that requires the assistance of a private investigator.”
"From my first contact with the people at Radius, they were extremely respectful and professional. They were able to explain to me exactly what they were going to do to help me and told me how much it would cost. Even better, they stayed under my budget and finished sooner than I had expected. I have spoken with many investigative firms in the past and will continue to go back to Radius if I need investigative services again. They were excellent in every way."
“As the owner of a security business installing surveillance and burglar alarm systems I had the pleasure of meeting Matthew. I can honestly tell you that over the past 7 years I have known him that he is a man that stands behind is word and is a true professional at what he does.”
Infrastructure Specialist at Festo – Doom Inc.
"I knew going in that the answers I was looking for would be close to impossible to get without going through the court system. Erin was not only very professional, but also very emphatic and talked to me as a friend and not just a client whose money she wanted. I hired another PI before RI, and they didn’t even put 1/8 of an effort as Erin did to help me. I was kept in the loop throughout the process and never felt like my case was being ignored. I would highly recommend working with Radius Investigation for your next project especially if you’re working with Erin."
“Even though I am experienced investigator, I rely on Radius for anything that happens in NY. They have quickly and more important, accurately supported my cases when it moved into the NY area or I needed a knowledgeable local investigator to gather documents”
"Outstanding investigative services, communication and resources! Great working knowledge and skill sets!"
“Matt is one of the best PI’s I have worked with. I get excellent results from his investigations that I have used to obtain a fair and reasonable settlement. He is very creative when it comes getting information on a subject. I highly recommend his services.”
“Matt was the first to answer my request in finding “my sister”. He told me I had the “key ingredients” (a lot of information) for a search, and that he would refer me to someone in Pennsylvania as his business is in New York. He made a contact while I was on the phone with him and asked the PI in PA to give me a call and the reason why he should contact me. I very much appreciated his time and his concern. I believe our conversation covered all the pertinent details in about ten minutes. Thanks, Matt!”
“These guys are amazing. Quality professional service at an affordable price. As an attorney, time and time again I’ve turned to Radius in desperate situations where I needed a quality investigator to immediately help me locate someone, or get papers served in a timely and no nonsense manner, and they have never let me down. I highly recommend them to anyone who needs an investigator they can trust to get the job done!”
“I hired Matt Seifer several times and all times he produced results in a timely manner and the results were extremely thorough and detailed. My Privacy was kept just that, private. I would highly recommend Matt Seifer for your business, legal and personal matters. I can be contacted for further details.”
