The reception staff were not very courteous when I asked questions and came across as dismissive. As someone who works for the health department, I understand how busy healthcare settings can be, but there is never a reason to be rude to patients. Professionalism and respectful communication are essential in healthcare. I actually needed to return for additional services, but because of this experience, I chose to go to a different location in the City of Orange instead -- and it was the best experience ever. The difference in customer service was very noticeable. I hope this feedback helps improve future patient interactions.

I have always coming to this location for lab work due to the convenience, professionalism, and…read morecompetence of the staff. I've even recommended this place to friends and have brought my daughter here in the past when she needed tests. However, our recent experience on October 3, 2025, was very disappointing. The woman in the photo provided unprofessional and rude service. My family has always used the same insurance card at this facility without any issues. I had just completed my own lab work at this location shortly before, using the exact same card, with no problems. In fact, even last year, my daughter had used this same card at this location without issue. But this time, the front desk staff claimed that my daughter's insurance was not valid and insisted that she provide a different insurance card. My daughter called me, confused, and I was genuinely surprised. I immediately contacted both my doctor's office and hers, and they confirmed that the insurance is valid and that the member ID number can be used to verify coverage. What upset me most was that the front desk staff spoke to my daughter in a harsh and disrespectful manner, even though she calmly explained the situation. Despite being told by both doctors' offices that the card was active and accepted, the staff refused to acknowledge it and did not allow her to proceed with the lab work. Her appointment was at 11:00 AM, but after a long wait and no resolution, she had to walk over to her doctor's office to have them call the lab directly. By the time she was finally allowed to proceed with the blood draw, it was 12:00 PM. At that point, she was told the lab was closed for lunch and was asked to return after 1:00 PM. She ended up having to fast and wait over two hours just to complete a basic blood draw , all because of the unprofessional handling by the front desk staff that day. In healthcare, professionalism, compassion, and patience are essential. I sincerely hope this feedback leads to better service and improved staff training at this location going forward.

Checking in was a breeze, they have self service kiosks. All questions and directions for a new photo of ID and insurance card were pretty straight forward. I made an appointment for 10:10am and was helped out pretty quickly after my arrival. Appointments are available to make online, walk-ins are welcome but there will usually be an extended wait. Blood draws haven't always been easy for me, but over the years I've been able to hop that mental hurdle. Even then, my heart always beats a little bit faster when I enter a lab. I was greeted and helped by Samantha, a most kind human and wonderful phlebotomist. I think she could sense my nervousness and kept the conversations flowing. She answered all my questions and was super patient. Most importantly she didn't hurt me and she got me on first poke. YAY! My doctor had requested a blood draw and a urinalysis. I recieved an email that my general labs were ready next day. Quite quickly, especially when they average 2-5 days! I did have a specialty/genetics test that promised results in 2 weeks or more. I recieved them right in the 14 day mark! I appreciate the punctuality! From my experience, this is my favorite lab to go to when I need my labs ran. Will be back! Side note, as of right now (April 2026) they are re-doing the parking lot, adding solar panels and coverings. I'm assuming the project goes into the fall. Parking has been crazy. My primary care doctor and women's health doctor share the same lot, it has not been fun trying to park. I'd come at least 15 minutes early!

I had a very frustrating experience at this clinic when I took my daughter for lab work ordered by…read moreher doctor. She was required to fast before the appointment, so we came early in the morning before school. We waited almost 3 hours in the waiting room. When I finally asked what was happening, the staff told me they had skipped my daughter because they did not know how to pronounce her name. No one had called us or tried to ask. Another major issue was communication. The receptionist did not speak English, and no one in the clinic seemed able to communicate with us in English. This made it very difficult to ask questions or understand what was happening. After the labs were finally done, I asked for a simple doctor's note for my daughter's school since she missed the morning due to fasting and the appointment. The receptionist said she did not know what that was and could not provide one. Overall, the long wait, lack of communication, and inability to provide basic documentation made this a very stressful experience for both me and my daughter. I wish I can give it 0 stars .
