We had our first visit with PDA yesterday, and I was blown away. Very Kind and helpful front office staff! We were coming from a pediatric office that was quite the opposite, so it was very refreshing! Dr. Campbell and Paris went above and beyond my expectations of what we were looking for in a pediatrician and staff. So friendly, personable, great with children but also super easy to communicate with as a parent. The whole visit my kiddos were laughing and smiling, my son even said “that is the best doctor I’ve ever had!” As a mother what more could you ask for? Looking forward to my children growing up with this practice.
We love Dr Campbell and his staff. From the front desk to his nurse and the lab techs! Everyone is so kind and helpful. Dr Campbell is so knowledgeable about everything we have been through with him and even saved my daughters life by acting fast and sending her to the ER from his assessment findings. He follows up promptly and even calls us himself with test results. Could not ask for a better Dr or staff!
Dr. Campbell and his staff were absolutely the best. They got us in for an appointment immediately. The staff were kind and laughed with us. They all seem to genuinely enjoy their job. We were able to get our testing done on site and results within just minutes. Dr. Campbell seems to connect with the kids and knows exactly what’s going on. Top notch from start to finish. 10 out 10 recommend to anyone and everyone I know.
We have loved our experience at PDA! We see Dr. Tonia Cox for our child. She is the most friendly doctor I've ever met! She is so knowledgeable and takes great care of our kid. She's never in a hurry and takes time to answer all of our questions. The office as a whole is also great. When our little one had an ear infection that wasn't getting better after trying antibiotics, we called on a Saturday but they were booked up. We asked them to notify us of cancellations, and a few hours later they said they'd had a cancellation and could see us! We were so grateful.
Both of my kids have been seeing Dr. Cox since birth and we only have wonderful things to say! We trust her to guide and support us through every stage. She’s extremely knowledgeable, kind, gentle, and very caring. We’ve seen a few other doctors in the practice when our kids were sick, and they were also phenomenal. I have and would recommended Dr. Cox and this practice to anyone looking for pediatric care.
