I've had really good luck with this agency! Stephanie, my agent, is awesome. She really goes above and beyond to make sure you're happy and getting what you need from your nanny. Living in Irvine/Orange County, there is a high demand for live-in nannies and good help is always hard to find! You will find that most nannies are from mainland China, but there are also ladies from Hong Kong, Taiwan and Indonesia. Some can communicate a bit in English and have experience with non Chinese-speaking families. We used this agency in preparation for our 3rd baby....Stephanie helped us find our zuo yuezi nanny as well as another live-in nanny to take over after the first month. We have been very happy. Stephanie is always a phone call (or text!) away, is very easy to contact and has reassured us that she will work hard to find a replacement if we are unhappy. Thankfully that hasn't been the case so far! But it's good to know Stephanie is used to working with typical/demanding OC mommies! The agency pre-screens candidates and ensures they have a current health assessment (physical exam) and vaccinations. If certain items need updating, I have found CVS/Minute Clinic to be a great resource (i.e. your nanny needs a TDAP, ect). Even though the office is in Monterey Park, you can video chat with prospective candidates using WeChat or WhatsApp. This has been especially helpful for us since my husband is super busy with work! And it has saved us the drive out to LA! I would highly recommend this agency to help you find a great, reliable nanny for your family!
