I spoke with Gerald over the phone and let me just say he was the nicest most helpful person. I give him two thumbs up. Keep up the great work Gerald.
By Cassandra
Gerald was very kind and encouraging as to what I needed to do to get my interlock device. We lost connection but I was able to get him back on the phone.. he was very helpful and professional!

I called Guardian not because they were the closest location, but because of my peers experience with the interlock company. When I called to get an appointment and I had the far-fetched idea to schedule for the next day. Gregory Frakes went over and above in a brief but efficient manner and absolutely exceeded my expectations and found a way to get me what I wanted. I look forward to this kind of service in a more stressful than not situation.
