This Nurses Week, we pause to recognize the compassion, dedication, and resilience that nurses bring to every patient, every day.

Behind every moment of care is a nurse who chose to show up — to comfort, to advocate, and to make a difference when it matters most.

Today, we invite you to join us in thanking a nurse who has impacted your life. Whether it was a small act of kindness or a life-changing moment, their work never goes unnoticed.

To all nurses: thank you for the care you give, the strength you show, and the lives you touch.

Happy Mother’s Day to all the moms out there, especially Linda! You’re the glue that keeps us together and holds us acco...
