Chisholm Trail Pediatrics Georgetown has been in its current location since May 2007.  We have been blessed to serve the Georgetown area for over 20 years.  

The current building was designed by founders Dr. and Mrs. Ramsey with a nod to the nostalgia of the Texas Prairie we now live on, and the nearby route for  The Chisholm Trail cattle drives that took place from 1867-1884.  Construction on the building was completed and we moved from our old University Avenue strip mall location to our beautiful Texas country style office in 2007.  

When our ownership changed hands in 2018, we rolled out a new western themed logo and updated some of the exam room themes, and converted to electronic medical records.  These changes have enhanced the professionalism of the practice, yet maintained the history of the open Texas Prairie and of the beginnings of CTP.  We hope you will feel at home with us!   

We strive to provide exceptional pediatric primary care to ages 0-18.  Services provided include wellness exams, immunizations, urgent care and illness visits.  Same day appointments are available for existing patients who call before 3:30pm.  

Our largest clinic is home to six providers;  Drs. Flachs,  Cavanagh and Wilson as well as Pediatric Nurse Practitioners Miranda Afsharirad, Raquel Goytia and Brittany Eichhorn.  We encourage you to meet them all.  If you have a favorite provider, be sure to request them when you call for an appointment.

Andrew Cavanagh, MD - Owner

"My approach to practice involves teaching and including the parents in the decision process.  At the same time, I use plenty of humor to put the children at ease...and it's more fun that way!"

Born in Chicago, Dr. Cavanagh got here as fast as he could, moving to Texas at the age of 4.  

He earned his undergraduate degree in genetics at Texas A&M University.  After graduation, he spent a year in China studying culture and language at a university.  He returned to the US to attend medical school at Texas A&M and continued his training as a pediatric resident at the University of South Carolina.  

Dr. Cavanagh and his wife moved to Austin eleven years ago and he has practiced pediatrics in the area ever since.  In his free time, he enjoys playing with his three children and getting his wife to laugh at his silly jokes.  His family most recently traveled to China to bring home their newest member, their adopted son.  His hobbies include reading, writing, (he co-authored a college textbook) drawing, and Bible study.  He is a record-holding powerlifter and a self-proclaimed comic book geek.
