“Be the reason someone smiles today.” -Unknown

Here at Pillar Primary Care, we value our patients and staff as we walk the journey of optimal health together. Today, we received a lovely drop-off of flowers from a dear patient and want to remind everyone to do something kind for others today. It truly is the little things in life that makes the greatest differences for folks.

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.

Please share this post with any dietitian who might be interested and have them contact the office at info@pillarpc.com for more information.

Happy Easter From Pillar Primary Care

“He has risen; he is not here.” Perhaps the most profound words ever spoken. The Son of God, Jesus, died, was buried, and overcame death as he promised. A turning point in humanity, where a holy and just God sat in judgment of sin and became the justifier through Jesus’ sacrifice redeeming His people back to himself. Celebrate today the glorious truth that ‘he is risen; he is not here’!

“When the Sabbath was past, Mary Magdalene, Mary the mother of James, and Salome bought spices, so that they might go and anoint him. And very early on the first day of the week, when the sun had risen, they went to the tomb. And they were saying to one another, “Who will roll away the stone for us from the entrance of the tomb?” And looking up, they saw that the stone had been rolled back—it was very large. And entering the tomb, they saw a young man sitting on the right side, dressed in a white robe, and they were alarmed. And he said to them, “Do not be alarmed. You seek Jesus of Nazareth, who was crucified. He has risen; he is not here. See the place where they laid him. But go, tell his disciples and Peter that he is going before you to Galilee. There you will see him, just as he told you.” And they went out and fled from the tomb, for trembling and astonishment had seized them, and they said nothing to anyone, for they were afraid.” Mark‬ ‭16‬:‭1‬-‭8‬ ‭ESV‬‬

And they went out and fled from the tomb, for trembling and astonishment had seized them, and they said nothing to anyone, for they were afraid. [Some of the earliest manuscripts do not include 16:9–2

Many years ago I created four celebration boards to encourage patients as they acheive milestones of success towards better health. Today, I restarted that tradition at Pillar PC with a new set.

With each milestone, patients are invited by their physician to publically sign their name showcasing their accomplishment. These boards represent a reminder to what has been achieved to those who need refreshment and what can be achieved to those who need encouragement.

It is only fitting that the very first signatory for these new boards was able to sign all four at once.

About 15 months ago Mr. M received a diagnosis of diabetes. This came about as part lifestyle and part medication side effect. He and his family vowed a change. Now 50 lbs lighter, with normalized numbers, off a couple medications, and the reversal of the diabetes diagnosis, he is crushing it. As a result of his hard work, his underlying health concerns have improved and he told me today that he received two very impressive performance rewards at work. His body just works better now. (And his kids are asking for more spinach at dinner!)

At Pillar, we are commited to your success. We will walk with you every step of the way. We’ll brush you off when you stumble, cheer you on as you overcome a challenge, and celebrate when you succeed.
