Mental health is an important part of overall health. Taking time to care for your mind can help improve sleep, relationships, energy, and physical well-being.

During Mental Health Awareness Month, our care teams encourage everyone to check in with themselves, practice self-care, and reach out for support when needed. Talking openly about mental health helps reduce stigma and strengthens our communities.

A hospital experience is shaped by more than medical care. It is also shaped by kindness, compassion, and the small moments that make patients feel supported.

During Patient Experience Week, we recognize the teams across our hospital who help make care more personal and meaningful. From nurses and physicians to support staff and volunteers, every interaction helps create a healing environment for our patients and families.

We are also grateful for the patients and families who trust us during important moments in their lives.

Volunteers bring warmth, kindness, and compassion into hospitals every day.

Across the country, millions of volunteers give their time to support patients, families, and healthcare teams. In hospitals, their presence can make a meaningful difference by offering comfort, guidance, and a friendly face when it matters most.

This National Volunteer Month, we celebrate the individuals who generously share their time and energy to serve our community.

St. Mary’s Hospital, a member of Prime Healthcare Foundation, has been recognized nationally for excellence in emergency care, earning a 4-Star Top Performer designation for Overall Emergency Department Care and an Award of Distinction from Professional Research Consultants.

This recognition places the hospital among the top 25% nationally and reflects the experience patients receive when they need care most. From moments of urgency to times of uncertainty, the Emergency Department team is committed to providing care that is not only timely and effective but also compassionate and respectful.

For more than a century, the Emergency Department has remained open to serve the community, continuing that commitment every day. That dedication was especially evident in recent weeks as teams cared for patients following the March 10 tornado, reinforcing the hospital’s role as a trusted resource during times of need.

This achievement also builds on continued recognition for specialized emergency care, including Geriatric Emergency Department Accreditation, reflecting a focus on meeting the unique needs of older adults.

This recognition is a reflection of the teams who show up every day ready to care for their community.
