    Horrible! Quest sent a login link via sms. I checked in according to their instructions. I waited and was never called. No one to talk to - no front desk so I tried to speak to someone when they opened door to call someone else... Women was horribly rude... When I asked to speak to someone in charge that woman was equally rude. According to them it was all my fault for using the link they sent. Finally they agreed to see me but then sent me to the lobby to wait again. In total I waited over an hour past my appointment time. Thankfully there was one young man who was very helpful who finally brought me in took care of the testing quickly efficiently and my thanks to him for that but overall there's no way I will ever come to this location again.

    Jacob was very personable and highly skilled. He explained things to my 11 year old son as he drew my blood and before he drew my son's blood (his first time) in a way that was calming and interesting.

    I was tested by Maria M, and unfortunately my experience with her was not pleasant. Her communication style felt very authoritarian and abrupt. She often spoke in very short responses and did not complete full sentences. For example, when the form required a signature, I asked if I could use my initials. She simply replied, “Sign,” without any clarification. Additionally, there was no greeting when I arrived and no acknowledgment or “thank you” when I left.

    I had a very disappointing experience today at Quest Diagnostics - Peterson Ave. The laboratory had previously made a mistake with our blood test order, which required us to return for a repeat visit. I came prepared with the written request form clearly stating which blood test I was there for. Although the correct test had originally been submitted, the lab made an error processing it. When I tried to calmly explain the situation to the mid-aged staff member assisting me, she immediately became rude, raised her voice, and insisted that the lab could never make a mistake. She repeatedly blamed my provider instead of listening to what I was saying. I made it clear that I wasn’t blaming her personally, but she refused to hear me out. She began yelling, threatened to have me kicked out and trespassed, and created a scene in front of other patients. Even after I brought in a new order, she continued to argue and would not listen. When other staff members attempted to step in and help, she stopped them, saying it would be an insult to her if someone else assisted me. Thankfully, the manager eventually came, listened to my side of the story, understood the situation, and arranged for another staff member to complete my visit. However, the original employee continued to display a hostile attitude toward me from the back area. This was one of the most unprofessional healthcare experiences I have ever had. Patients deserve to be treated with respect, especially when they are simply trying to correct an error that was not their fault. Due to this experience, I will not be returning to this location.
