Dr. Perez-Tselikis aka Dr. Perez or Dr. Jackie Perez has been my children's pediatrician since…read moretheir birth. After my son turned a year old, she had him checked through a simple blood test for Fragile X Syndrome (long story), in which he was diagnosed after results coming back positive! I can bet most pediatrician In THE NATION don't even know or the very least think of Fragile X Syndrome! I bet if I had another doctor, they would have probably just given my son the general "Autism Spectrum Disorder" (ASD) diagnosis, which many if not most often do, and would go as far as to say, some, if not a good deal, may actually have Fragile X Syndrome (FXS), which is, actually the number one genetic cause of Autism, or even something else, but had never had the adequate medical guidance to be checked! Dr. Perez caught this at one year of age, helping me start a regimen of therapies and not losing precious time! She always answers our questions and concerns, and is patient with us. At times she might be quick with her prognosis, but it's only due to 30+ years of experience in the practice, and has seen just about everything. Plus, if we have any concerns or doubts, she is flexible and pro active in covering any needed bases. As a mother, I worry, and Dr. Perez is always there to make sure my children are healthy and doing well, or if any modifications need to be made, or if they're sick, quickly get a plan of action going to get them better as soon as possible. We've been with her for well over a decade, so I think I can speak candidly regarding her review. Additionally, her nurses are wonderful, and the staff is helpful, friendly and kind. Yes, during peek seasons, predominantly winter, there might be a bit of a hold on the phone to schedule an appointment, and likewise have a bit longer wait in the waiting room, but during those times, it's something to be expected not just at Desert Valley Pediatrics, but clinics (adults too) in general. However, I usually can schedule an appointment on the phone in less than 10 minutes, and our wait times don't usually exceed anything more than 10-15 minutes, it just all depends on the day and the demand- good doctors might run late because they actually care and take the necessary time with each patient- good doctors are worth the wait, and Dr. Perez is worth the visit. The facilities at each of the three locations I've been to are separated by well and sick waiting rooms, which is nice, but then you get called to the back and at times have to pass by other patients, so nothing, of course, is 100% separated. The murals throughout each clinic are beautifully painted and create a nice distraction for some, however some of the rooms are in need of a deep clean (walls, baseboards, etc. - things not quickly noted on a daily basis), but overall are generally clean and well maintained. Overall, I strongly recommend Dr. Perez and Desert Valley Pediatrics, who have other good physicians worth looking into, especially when/if Dr. Perez is away and you need a back up doctor. ;) Hope this helps. :)
