Brenda Sadeghi is a true Los Angeles native. However, she grew up in Tulare, California.

She especially treasures what she calls the “oh moments” in the classroom. “I love teaching when the vast majority of the class has little experience with the concept because when they start to understand the concept, they often say, ‘Oh, I get it!’ Then I feel our experience has come full circle,” she explains. In her spare time, the Lake Balboa resident enjoys trying new things such as parasailing and kayaking. She also seeks out local destinations where she can experience different cultures and traditions.
