    We have been going to this Quest branch since El Portal G St Quest is being remodeled…read more They have professional staff , courteous & accommodating:) thank you for your services! All Quest laboratories we go have exceeded their excellent services ( so far ) the place is clean & they definitely observe Covid precautions!

    If you wish to have no customer service then by all means go here. You are greeted by computers…read moreonly, no receptionist. My 86 year-old husband navigated this system unsuccessfully and someone did evidently help him finally. But we were unable to download the blood test results because someone input his birthdate incorrectly (which would have been someone else other than him as he is not computer competent, nor can he see or hear very well). So I attemped to get a copy from Quest (in Merced). After waiting too long, (20-30 minutes) to speak to a human, I had to interupt one of the staff that was ignoring me when collecting other patients. They do not have a recepitionist! They claim to lack access to results. So, she handed me a card with a phone number so that I could call to get the birhtdate changed online which meant another 30 minutes or more of my time to correct an err we did not make. Still do not have the results. I chose to spend my time looking for a more humane service. I refuse to accept my husband or myself being treated like a cyphers (One having no influence or value; a nonentity)! The Management should be ashamed of implementing such inhumane delivery methods.

    Helena was professional, prompt and so educational with our potential mold situation at our new…read morehouse. We hired her and she responded before 7 am and we scheduled a time for her to come out. Although when our insurance got involved we realized we needed to do their protocol, Helena would have been a welcome support for our situation and after multiple back and forths--we were convinced she was our person. I researched all the mold experts and looked for certification, independent testing and someone who isn't connected to remediation services--which can be a conflict of interest in results. She checked all my boxes. I wouldn't hesitate to reach out and hire her again if another situation were to arise. She was also very respectful of our budget, educational and helpful rather than provoking fear or urgency--which by the way can be a red flag for this type of work. That means she is a reputable and ethical expert who values customer service and people above all else.

    After submitting a biological sample that showed signs of mold illness and an ERMI test around our…read morehouse showing high levels of mold, I was in a panic. I contacted Central Valley Mold Experts and Helena responded incredibly quickly. We scheduled an appointment for the next day and she was on time and so friendly. She did a thorough inspection of all the spaces in our home using multiple measures to check for moisture issues. We also ran some air samples to be on the safe side. Helena explained everything clearly and thoroughly and truly set my mind at ease. I would not hesitate to hire her again for in the future. Thank you, Helena!
