Serious concern with DOT testing procedures at this location. I arrived about an hour before…read moreclosing for a urine test and was not properly informed of the full 3-hour "shy bladder" process required under DOT regulations. Staff told me I only had until their closing time instead of the full window, and I was never clearly advised that leaving early could be marked as a refusal. Because of this, the situation appears to qualify as a collector/procedural error. Cutting the process short due to business hours and failing to properly inform the donor is not acceptable when handling federally regulated tests. This is not just poor service--this directly affects people's livelihoods. I have proof of my arrival and departure times. If you perform DOT testing, you are expected to follow proper procedures, not convenience. Updating my review after speaking directly with the lab. Instead of addressing my concerns professionally, the situation escalated. During the recorded call (after informing them it was being recorded), I was told: "You can come get a second test... read between the lines... you know the address, pull up if you want to." Given the context, this came across as a threatening and highly unprofessional statement rather than an attempt to resolve the issue.

They only caused stress, anxiety, and waste of time. Very poor communication and they only used excuses that they will have it certain date and time and when it comes to the date and time they don't won't answer you or they come with another excuse. I asked them for my refund so they don't have to deal with me calling them and bothering them every day (vice versa) they won't refund me so in other words I lost my $485 and until now I have received the results. DONT GET YOUR LAB SERVICE DONE IN THIS PLACE. If I could give them NO STAR at all, it would've been great!

I had to get a Department of Transportation medical exam and drug test, and my company sent me to Real Occupational. They told me up front "our Doctor is real cool." They were right. I got in really quick, despite a waiting room full. Everyone was really friendly, with the slight exception of one of the ladies up front, but everyone has a bad day. There was even a glitch with my blood pressure, and they reassured me "don't worry, just come back and let's check again." I did and everything was fine (those two cups of coffee before I went in probably didn't help). Then Dr. Wall even explained why it was really common. No place is going to be perfect, but when you think of having to go to clinic of any kind, this is as good as it gets. Hopefully the previous reviewer will give them another chance. Definitely worth it.

This place is heavily unorganized. I called ahead of time and asked what time they closed. Spoke to…read morea lady and said 3:45 is the last patient because of COVID. I show up at 3:45 maybe a minute later and she said that they closed at 3:30pm and that FedEx had already left. Pathetic child like communication. They could have told me 3:30pm the first time and I wouldn't have came all the way from LA. Spoke to the office manager Juan. He made me repeat myself 4-5 times. If that's a manager then that explains why this place sucks. He said he would have made an exception if he was there and he surely was there and made no exception. Instead he was being a rude j**k. Shoot the 7 minutes we argued on the phone, he could have let me pissed in a cup but instead he felt like pissing me off. Would not recommend this place to anyone. If I was an employer, I would rather my employees piss dirty than to send them here. This place was just sold to some other company and looks like everything went to s**t. I requested my company to send me elsewhere other than this sh**hole with a bunch of sh**heads.

I reached out to Marshall GeoScience through Yelp…read more Marshall (the principal engineer) replied quickly--even continuing the conversation well after business hours and offering to jump on a call. I wasn't exactly sure what I needed at first, and he was incredibly patient while I tried to explain the situation. Rather than guessing, he took the time to understand my goals, clarified that a firm estimate would require a defined scope of work, and laid out what that scope should look like so I could move forward confidently. What stood out most was his clear communication, transparency, and willingness to help without any pressure. I'd contacted a few other firms before him and had mixed results. Marshall was by far the most responsive and helpful. If you need a geotechnical engineer who is prompt, thoughtful, and genuinely focused on setting you up for success, I highly recommend Marshall GeoScience.
