The journey in the organization was never easy, yet they carried their responsibilities with courage, passion, and unwavering dedication. 𝘌𝘷𝘦𝘳𝘺 𝘦𝘧𝘧𝘰𝘳𝘵 𝘵𝘩𝘦𝘺 𝘨𝘢𝘷𝘦, 𝘦𝘷𝘦𝘳𝘺 𝘴𝘢𝘤𝘳𝘪𝘧𝘪𝘤𝘦 𝘵𝘩𝘦𝘺 𝘮𝘢𝘥𝘦, 𝘢𝘯𝘥 𝘦𝘷𝘦𝘳𝘺 𝘮𝘰𝘮𝘦𝘯𝘵 𝘵𝘩𝘦𝘺 𝘤𝘩𝘰𝘴𝘦 𝘵𝘰 𝘴𝘦𝘳𝘷𝘦 𝘥𝘪𝘥 𝘯𝘰𝘵 𝘨𝘰 𝘶𝘯𝘯𝘰𝘵𝘪𝘤𝘦𝘥. Their hard work is 𝙨𝙚𝙚𝙣, 𝙙𝙚𝙚𝙥𝙡𝙮 𝙖𝙥𝙥𝙧𝙚𝙘𝙞𝙖𝙩𝙚𝙙, 𝙖𝙣𝙙 𝙩𝙧𝙪𝙡𝙮 𝙫𝙖𝙡𝙪𝙚𝙙.

They have not only been leaders—they have been inspirations, voices for the environment, and examples of what it means to care beyond oneself.

We would also like to give special recognition to 𝙔𝙀𝙎-𝙊 𝙋𝙧𝙚𝙨𝙞𝙙𝙚𝙣𝙩, 𝙐𝙧𝙞𝙚𝙡 𝘾𝙝𝙖𝙧𝙢 𝙏. 𝙍𝙚𝙮𝙚𝙨, for her remarkable efforts and unwavering optimism in leading the organization. Her strength, positivity, and commitment have guided her members through challenges and successes alike, leaving a lasting impact on everyone she has led.

As they move forward to senior high school, may they carry with them the same fire, the same purpose, and the same heart for service. May they continue to rise, lead, and make meaningful change wherever life takes them.

This is not just an ending—it is the beginning of something even greater.

We are so proud of you, Ate’s and Kuya’s! ✨💚

The YES-O Officers of Don Sergio Osmeña Sr. Memorial National High School, together with their adviser, recently visited SM Seaside as part of their Trash-to-Cash Program. Through this initiative led by our YES-O President, Uriel Charm T. Reyes, the organization collected PET bottles and other recyclable materials from the Grade 7–10 Science class students who are members of the organization. These materials were gathered and brought for proper recycling, turning waste into something valuable while helping reduce the amount of trash that ends up in landfills.

This activity is a small but meaningful step in preserving and protecting our Planet Earth. By recycling and practicing proper waste management, we contribute to reducing pollution and conserving resources for future generations. It reminds us that helping the environment does not always require grand actions—sometimes it begins with simple habits like collecting recyclable materials and being responsible for the waste we produce.

The YES-O organization hopes that by the next school year, this initiative will grow even bigger—with all students in the school contributing to the Trash-to-Cash Program. Together, we can build a community that actively works toward sustainability and environmental stewardship.

Let us continue to take part in protecting and preserving our only home—Planet Earth. Every bottle recycled and every act of responsibility brings us one step closer to a cleaner, greener, and more sustainable future. 🌱🌍
