Welcome to Our Practice!

If you are looking for a high quality, compassionate and family-oriented pediatric practice in the Trinity area, you’ve come to the right place.

We began our practice here in 1997 as a husband-and-wife team. Over the years our practice has grown, and we have been fortunate to add another excellent Pediatrician as well as two outstanding Pediatric Nurse Practitioners. As parents ourselves, we have designed our practice to be as child and family friendly as possible.

As a small group we offer personalized attention and consistency of care. When you call us to make an appointment, get medical advice or request records on your child, you will speak directly with one of our staff within minutes. If your child is ill and needs to be seen, they can be seen the same day by someone who knows their history and will provide the best care possible. If your child has a complex medical problem, we will be personally committed to ensure that everything is done to help your child get the most state of the art care by working with the best specialists in the area.

During your visit, we will take the time to talk with you and listen to your concerns. We will provide the information you need to understand your child’s medical needs and equip you with the knowledge necessary for promoting a lifetime of optimal health and wellness. When you have urgent questions After Hours, you will be able to speak with one of us directly.

We invite you to take a few moments to browse our website and familiarize yourself with our practice. You will find helpful information you need including provider bios, special services we offer; such as, breastfeeding (lactation support)ADHD treatmentnewborn carecircumcision specialistdepression & anxiety treatment for teens, directions to our office, patient education materials and new patient forms.

We look forward to partnering with you on your child’s special journey of growth and development to adulthood.

  • "I recently reached out to Dr. Hasell on a Telemedicine call and I want to thank Dr. Hasell for helping me find ways to deal with my anxiety. He gave me links to articles, apps, and book suggestions to help lower my anxiety levels while also understanding why I suffer from anxiety as a young student and procrastinator. He was able to relate to me and was able to give me advice as well as show he follows the advice he gives so that I understand its benefits."
