Diane Harris

Founder & Partner

Diane has been in the hospitality business for over 35 years. She has been a server, a bartender, event coordinator and manager. Diane has held management positions in catering, and event production with the prestigious Fairmont, Marriott and Sheraton hotels.

The most rewarding position, and the most challenging, was working with cancer survivors and supporters on the Avon Breast Cancer 3-Day Walk. It was Diane’s responsibility to ensure the safety, security and comfort of over 7,000 walkers on their 60 mile journey. She accomplished this in San Francisco, Miami, Atlanta and Washington DC.

When she isn’t tending to her three dogs, Riley, Quincy and Rory, Diane can be found smashing whiffle balls on the community pickle ball courts, kayaking around the bay, and taking weekend trips in her little travel trailer named Trixie.

Diane’s goal at On Call! is to make temporary staffing a better place on both sides of the table.
