About Us

Longhorn Pediatrics was founded by Dr. Rodolfo Barrera and Dr. Larry Lewellyn in 2006. Dr. McMains began working at Longhorn in 2009 and purchased the practice in 2013. Our goal is to provide quality medical care with a family atmosphere for children from birth to 18 years and care for them as if they were our own. Creating an environment that encourages your child to feel comfortable during what can be a stressful time is important to our office. We aim to support you as parents and enable you to nurture a healthy child because you have your child’s best interest.


Longhorn Pediatrics offers a full array of services to help your child maintain good health. A few of our services include:

  • Newborn care
  • Sick visits
  • Well child visits/ Physicals
  • Pre-Partum appointments
  • Clinical triage / Referrals
  • After hours

5 reasons why Dr McMains should be your child's doctor

  1. Dr. McMains respects you as a parent
    When you bring your child to our office, you can expect to be respected as the first and foremost authority in your child’s life. Dr. McMains is a trained medical professional, but you are still the parent.
  2. Dr. McMains practice is inclusive
    Our client base is very diverse and we like it this way. We welcome families from all over Austin on a daily basis and they all feel comfortable when they’re here. Everyone here is treated with respect and are given the attention they deserve, especially in times of sickness, when the last thing you need added to your life is more stress.
  3. Our practice accepts most forms of insurance
    When Dr. McMains took control of the practice, it was very clear from the very beginning that this was going to be a place where children would be helped onto health again, regardless of their insurance policy. We are in network with most providers, including medicaid and chip.
  4. The practice is conveniently located
    We’re only a hop and a skip away from campus and downtown. We draw people from all corners of Austin and given where we are, it’s no wonder.
  5. Longhorn Pediatrics is a one-stop-shop
    When your child becomes a patient of record, you can tap into all the services we offer under one roof. From newborn care to high school physicals, it’s all here.
