About Hill Country Endocrinology & Primary Care
A Board-Certified Endocrinologist and a Family Physician, Working Together
Hill Country Endocrinology & Primary Care is a physician-owned practice. Dr. Andrea George treats diabetes, thyroid disease, menopause, osteoporosis and other hormone conditions. Dr. Shibu Oommen provides family medicine for adults and children. When you need both, your doctors are down the hall from each other and share one plan for your care.
We care for patients from Leander, Round Rock, Georgetown, Liberty Hill and northwest Austin.
Why we practice direct care. We don’t bill insurance for office visits. Instead, patients pay a simple monthly membership. That lets us keep our patient panels small, so your visits are unhurried, you can reach your doctor directly, and you always know what you’ll pay.
What your membership includes
- Office visits and follow-ups with your doctor
- Same-day or next-day appointments when you need them
- Direct access to your doctor by phone, email or video
- Lower cash prices we’ve arranged for labs, imaging and referrals
- Discounts for larger families and for employers
See our Endocrinology and Family Medicine pages for what each membership covers and current prices.
Meet our doctors
Andrea George, MD – Endocrinology
Dr. George is board-certified in internal medicine, endocrinology, diabetes and metabolism, and obesity medicine. She completed her residency at the University of Pittsburgh Medical Center and her endocrinology fellowship at Creighton University School of Medicine. She cares for patients with diabetes, thyroid disease, osteoporosis, menopause and hormone concerns, and weight management.
Shibu Oommen, MD – Family Medicine
Dr. Oommen is a board-certified family medicine physician who grew up in Sugar Land, Texas. He completed his family medicine residency through Nebraska Medicine and was a Clinical Assistant Professor of Medicine at Creighton University School of Medicine. He cares for patients of all ages, from well-child checks to managing long-term conditions, with a focus on prevention and staying well.
Because both doctors are in the same practice, patients with diabetes, thyroid or hormone concerns can have their family doctor and their endocrinologist work together. Endocrinology members can add primary care with Dr. Oommen for $99 a month.
What is Direct Care?
Frequently Asked Questions
For most people, yes. Your membership covers your care in our office, but not hospital stays, emergency care, surgery or other specialists. We recommend keeping a health plan for those bigger costs. Many members pair their membership with a high-deductible or marketplace plan, and many of our members use a health share. Health shares are not insurance, so check what yours covers.
Yes, you can use your insurance for labs and imaging. You can also choose the lower cash prices we’ve arranged with local labs and imaging centers, which are often cheaper than going through insurance.
Starting in 2026, federal rules allow people with an HSA to pay direct primary care fees from it, up to $150 a month for one person and $300 a month for a household. Some of our family plans may exceed that limit, so please check with your HSA administrator. Endocrinology consultation and visit fees can generally be paid with HSA funds too, and we give you an itemized receipt to submit. FSA rules depend on your plan.

Yes. Dr. Oommen accepts Traditional Medicare for primary care. Everyone else joins through a membership, including a $149 a month option for adults 65 and older without Traditional Medicare.
