About Joy & Crown

Medical practices are increasingly pressured financially by rising healthcare costs and expanding healthcare legislation, and in turn respond with attempts to expand their patient base by scheduling as many patient encounters in a day as possible. But what gets sacrificed in this incessant rush to get bigger?
For Dr. MaryEllen Cavalier and the staff at joy & Crown Pediatric Specialists, the goal is not to be the biggest. Rather, the goal is to be the best—to allow enough time in a patient visit so that all the important questions get answered, so that instructions and recommendations are clearly presented and absolutely understood, and so that even the smallest patients feel safe, valued, and ready for life’s opportunities and challenges. The goal is to be a true, patient-centered medical home, from cradle to college.
That is why Joy & Crown Pediatric Specialists endeavors every day to be North Texas’s premier pediatrics practice—where patients and their families are offered both expertise and empathy, convenient location and convenient scheduling and communication options, coordinated referral services with local, regional, and national leaders in pediatric subspecialties and, most importantly, continuity of care.

What our Families are saying

Dr. Cavalier was one of the most amazing doctors and people that I had ever met in my life. She was very professional, insightful, intuitive, attentive and caring. I was a patient of hers in the Children’s Hospital at MUSC in Charleston, South Carolina for a short time in 2005-2006. She was sweet and I have never forgotten her and how she treated me and took care of me during one of the most trying times of my life. She never was negative towards me or my family, she was always friendly and warm. She never lied to me about my situation and always told me what I needed to know, even if I was 16-17 and battling cancer. I would hope that one day I will meet her again to personally thank her, because she was nothing but a blessing. I know for a fact that she’s touched more people and helped so many before and after me. I’ve got a very blessed life because of her and doctors and nurses just like her, who were by my side 24/7. God has done a mighty work in my life and given me healing and I’m using this second chance to serve him and influence others, but there would have never been that chance had it not been for people like Dr. Jay Whittle, R.N. Julie Ireland, R.N. Theresa Gonzalez and my favorite, Dr. Mary. 🙂

Dr. Cavalier is everything you hope your Doctor will be while taking care of your children.
We love Dr. Cavalier to pieces. Starting seeing my son at 3 months old and she made the appointment all about him. Talking to him listening to him but also taking my input for what he couldn’t tell her. As a new mom these were important to me. She always answers every question and doesn’t make you feel like your crazy even if your worrying about something silly. She understands and takes care of my son as if he were related to her. He is turning 2 soon and I know we will be with her until he can’t see her anymore!

My son (5yr old) has always had MAJOR anxiety going to the Dr. He made it an absolutely miserable experience, for everyone involved, anytime we had to go. The very first time we visited Dr. Cavalier, I knew we were in the right place. He loves her and actually looks forward to his Dr. appointments now. She is excellent with kids and parents. The waiting room is so nice and clean, the office staff is wonderful and there is never a wait time in the waiting area or back in the room. I can’t sing enough praise about Dr. Cavalier and her fabulous staff!
