What People Say About Sandi:


Johnny Phoenix Cavazos

“I believe in you Ms. Castro.”

An orderly school board meeting room with an empty central podium flanked by neatly aligned microphones, each resting on matte black bases atop a long, light-ash wood dais. Nameplates with simple engraved titles, a small stack of policy binders, and a digital agenda screen in the background displaying “Pflugerville ISD – Place 6” in clear typography create a sense of organized governance. Cool, diffused overhead lighting and soft natural side light from narrow windows produce balanced illumination with minimal glare. The atmosphere is serious yet welcoming, emphasizing transparency and accountability. Composed from a slightly low angle toward the podium, with leading lines along the dais guiding the eye to the center. Sharp focus throughout, photographic realism, clean lines, and a neutral, corporate color palette.
