Welcome to Our Practice

We are pleased to announce we have a new doctor, Dr. Sheila Boes! She joined our practice early November and has been doing a wonderful job! The staff and patients love her. Dr. Boes is from Mississippi and did her pediatric training in Austin, TX. She has been practicing medicine since 1998 and has 3 children and a cat. Welcome, Dr. Boes!


Please call our office to check in for your appointment from the parking lot. Do not come inside the building without speaking to someone first. Thank you! 

Late clinic will be suspended effective immediately. Our office will now close at 5:00 pm until further notice.

***COVID-19 UPDATE*** Please read completely!

We will continue to remain open for care for all your family's health needs. Corridor Primary Care is taking added precautions with the goal of giving our patients and parents peace of mind until the COVID-19 (Coronavirus) pandemic is under control. We are in constant contact with the Hays County Health Department. As new information becomes available, we will continue to make changes and adjust our procedure as needed. The following steps are being taken in accordance with the current information and will be enforced until further notice.

We sanitize the exam rooms between each patient, and the waiting/common areas multiple times a day.

For all visits, we ask that you call us when you arrive to the parking lot, remain in your car until we call you back when it is your turn. Fewer people inside our building means less potential virus vectors. Masks are required on all persons over the age of 3 inside the building. 

As always, we continue to recommend practicing good hygiene. Wash hands frequently, and thoroughly. Cover your mouth when you cough. Stay home when you're sick. Avoid the elderly and those with severe health conditions whenever possible. Wear a mask. 

Thank you to being the best patients around! We are so fortunate to have such an understanding "Corridor Family."

Please refer to CDC.gov for more tips on how to best protect yourself and your family. You may follow us on Facebook for more up to date information that we may share.
