Yesterday, during our final staff meeting of the year, we proudly celebrated members of our Kudos Collective, perfect attendance honorees, employees reaching milestone years of service, and our retirees.

It was a meaningful opportunity to recognize the dedication, commitment, and impact our staff members continue to make at SMHS each and every day. From celebrating those with perfect attendance to honoring employees reaching 5, 10, 15, 20, and 25 years of service, the event highlighted the incredible people who help make our campus successful.

We also took time to honor our retirees and thank them for the years of service, leadership, and care they have given to our students, staff, and community throughout their careers.

As we close out the school year, we are grateful for the teamwork, professionalism, and heart our staff bring to SMHS every day. Thank you for all that you do for our students and our Rattler community.

Today, our seniors had the special opportunity to return to their former elementary and middle school campuses as they prepare for graduation.

Walking the halls where their educational journey first began was a meaningful reminder of how far they have come through years of hard work, growth, perseverance, and support from teachers, families, and staff along the way.

These walks celebrated not only the accomplishments of the Class of 2026 but also the connections and memories that helped shape them into the young adults they are today.

It was inspiring for younger students to see our seniors in their caps and gowns, serving as a powerful reminder that success, growth, and graduation are possible through dedication and determination.

We are incredibly proud of our seniors and look forward to celebrating them as they take the next step toward their future.

Our Culinary students had an incredible opportunity to learn from Matthew Bromley, a two-time Michelin-starred chef at the Michelin-starred restaurant Leroy & Lewis.

Chef Bromley visited SMHS to provide our students with guidance, insight, and real-world industry experience as they continue developing their culinary skills and preparing for future careers.

This experience demonstrated learning, collaboration, and career readiness in action as students gained valuable knowledge from a highly accomplished culinary professional.

We are grateful to Chef Bromley for investing his time, expertise, and encouragement into our students while helping inspire the next generation of culinary professionals.

What an amazing opportunity for our Rattlers to learn from one of the best!
