About these photographs

Every photograph on this site was taken during my own Ontario school-based experiences. Each is associated with a school based on where the file was recorded, never on visual guesswork.

Of 67 photographs reviewed, 27 are shared publicly. 34 are withheld because they show identifiable students, student names, or other personal information, and 6 are withheld as duplicates or as images too weak to serve as professional evidence.

Withheld photographs remain unaltered in my own records. Nothing has been blurred, cropped, or edited to make it publishable.
