Isabel Humphrey has practiced law in Arizona for over thirty years, most recently at Hunter, Humphrey & Yavitz in Phoenix, where she often worked closely on cases with attorneys from Aspey, Watkins & Diesel. She joined AWD in 2025 as her partners in HHY were winding down their practices toward retirement.
Ms. Humphrey has represented a wide variety of clients in her civil practice, from hospitals, general contractors and charitable organizations to entrepreneurs, injured students and landowners. Currently, she focuses on state and federal appeals and appellate consultation, while continuing to practice civil litigation at the trial court level.
Ms. Humphrey enjoys learning foreign languages and playing Irish music, both in traditional seisiún groups and in her Irish punk band, Whiskey Famine. She experienced her fifteen minutes of fame in 2012 when she obtained the computer records showing that Casey Anthony had searched “foolproof suffocation” on the day of her daughter’s disappearance.
