    Long wait. Not friendly. Save yourself a headache. Go to Labcorp. Or anywhere else but here.

    It is literally impossible to speak with a human being here. The concept of customer service is nonexistent.

    too busy, poor customer service. Make an appointment and they'll call you back 30-1hour later.

    They are very quick. Make an appointment and don't be late. Unfortunately no reception so if you have a question good luck!

    Review for Ms. Nancy Diaz and Quest Diagnostics, 2250 S. Main St., Corona, CA…read more Ms. Nancy Diaz is truly exceptional. She is caring, gentle, and very professional. Her warm and calm manner immediately puts you at ease, and she works with such confidence and skill that the entire experience feels comfortable from start to finish. I appreciated how kind she was and how she explained everything clearly. She is outstanding at what she does. This Quest location is also excellent. It is very clean, organized, and efficiently run. Because appointments are required, there is essentially no wait time. Check-in is quick, and you are seen almost immediately. The whole process is smooth and respectful of your time. Quest is very fortunate to have Ms. Nancy Diaz caring for patients at this location. I highly recommend this office.

    I have been at Quest for approximately four hours on the standby list. I completely understand that…read morepatients with appointments take priority and that being on standby means there is no guaranteed wait time. That is not my complaint. My complaint is the way Latonya treats people who do not have an appointment. She is rude, dismissive, and makes you feel like you simply do not matter because you are a standby patient. People are coming here because they need lab work done, and everyone deserves to be treated with basic courtesy and respect, appointment or not. During my four hours here, they were only calling approximately two standby patients per hour, and at one point roughly 90 minutes went by without a single standby patient being called. After waiting patiently for that long, asking a simple question about the wait should not be met with attitude. I understand being busy. I understand appointments come first. What I do not understand is treating people as though their time and concerns do not matter simply because they walked in without an appointment. Better communication and basic kindness would make a huge difference.

    We have three kids, now all adults, and have been coming here for years since they were young…read more We've been here for everything from sports physicals and injuries to sick visits, and all of the doctors and PAs we've seen have been thorough, knowledgeable, and great with all of us. There have been times when the wait was long, even with an appointment, but other visits have been quick. Regardless, the wait has always been worth it because we've consistently received great care. It's hard to find a place you trust for your family over so many years, and we've always been very happy with the care we've received here. Highly recommend!

    Called in this morning to due to an extremely painful and uncomfortable UTI and the Receptionist…read moredid a wonderful job thoroughly answering my questions and successfully guiding me on how to schedule a Telehealth appointment through their Website to help me get seen as quickly as possible to through the comfort and convenience of my own home! I really appreciate how professional and well trained the Receptionists are here in Communication and instruction etiquette. They were so patient and friendly in explaining how the online Website works and showing me how to navigate the different options online. My first Telehealth appointment was an easy and pleasant success thanks to the terrific Teamwork of the Company and I really appreciate how easy and smooth the online scheduling process is! I definitely recommend scheduling Telehealth appointments for UTIs, it saves so much time and resources eliminating the commute and office wait and the Telehealth Providers are super knowledgeable, caring, and expert Communicators in explaining clearly to me how to heal efficiently from my UTI and take better precautions from preventing them from occuring again in the future!
