Health insurance premiums are skyrocketing. What if you could get 90% of your day to day health needs taken care for less than a coffee per day?

We’ve all experienced where having health COVERAGE doesn’t actually get us health CARE. At Pillar PC, you have direct access to your doctor and their staff by text, email, and phone. There are no copays for visits and many labs are included free with membership. We also offer on site medication dispensing at wholesale price that usually beats GoodRx and retail store discounts.

Given us a call and check out our website at pillarpc.com to learn more.

Seed oils like canola, soybean, and corn oil might be in everything, but they’re not doing your body any favors. High in omega-6 fatty acids, they can drive inflammation when overconsumed, potentially increasing risks of heart disease, obesity, and other chronic issues. They’re often heavily processed, stripping nutrients and adding harmful compounds. Swap them for healthier fats like olive oil, avocado oil, or butter for better balance and less oxidative stress. Your body will thank you!

It's been an exciting Friday! I've been able to celebrate with several patients today in their health journey success.

One patient reduced his insulin level substantially which allowed for 10lbs of weight loss and a normalization of much of his blood work. He could not wait to tell his adult daughter the good news. She has been his biggest supporter and strongest accountability.

Another patient was down 60lbs, reversed (cured!) his diabetes, stopped his diabetes medication, and is more active and energetic than ever. He's doing amazing and ready to push the limits even further!

If you're ready to change your life and health for the better, give us a call. We'd love to help. -Dr. McColl

We're hiring!

Pillar is looking for a part time dietitian to work directly with our members in one on one counseling. Our nutrition program advocates for a real food diet limiting carbohydrates and promoting protein in order to reverse insulin resistance, cure diabetes, and promote weight loss with health restoration. It's a fun, tight-knit community of staff and participants who learn and practice this together.
