Horrible customer service, the office is disgustingly filthy and the person Abraham who actually takes your DNA sample is rude, dismissive and extremely unapproachable. He treats his clients like they absolutely do not matter and feels no need to address them and/or answer any of their very simple questions. If you question him and quite possibly become frustrated he will refuse service. He does not seem to care about his customers, his practice or the standard of professionalism that should be set forth in his line of work. After all, he is actually collecting a persons DNA samples. My impression is that because he is set-up in an extremely poor community he actually has no concern for them other than to make money. Also, be prepared to wait and have no one answer any of your questions.
