About Devonie Davison
I specialize in crafting films that bring your vision to life. By capturing the unique moments that often go unnoticed, I infuse my signature “Slick & Slimy” style to create a one-of-a-kind masterpiece that can never be replicated. I’m passionate about my work and committed to exceeding expectations, ensuring that every client is not only satisfied but truly impressed.
In addition to being a videographer, I’m also a professional boxer. My fighting style—fast and slick—served as the inspiration behind the name “Slick & Slimy.” To reflect both my craft and my active career in the ring, I chose a boxing ring as the logo for my brand. This combination of precision and creativity drives everything I do.
About Alexandra
From the start of my career in education, my goal has always been to be a cheerleader for students, offering unwavering support as they navigate their academic journey. My time as a school counselor has granted me a unique perspective, allowing me to see education through the eyes of my students. Over the years, I’ve had the privilege of working with students who have faced unimaginable trauma and obstacles—challenges that many of them have had to endure at a young age. Their resilience and inner strength continually inspire me to work even harder to help them pursue their dreams of higher education.
As a leader, my mission is to eliminate the barriers that hinder students from achieving their goals and realizing their full potential. As part of the HonestGainzz team, my aim is to unite families, schools, and communities in fostering lifelong learning through comprehensive, wrap-around services for students. To achieve this, collaboration, compassion, ethics, and transparency are essential. By creating a supportive network between school and home, we can empower students to attain and maintain grade-level proficiency, preparing them for postsecondary education and future careers.
With nine years of experience as a School Counselor in both the Bay Area and Central Valley, I have worked across middle and high school settings, supporting a diverse student population. I have also completed the necessary requirements to transition into administration, further broadening my ability to advocate for and support students in meaningful ways.
