Customer Support
General Manager
Diana Ocasio, General Manager
My name is Diana Ocasio and I have been with Cornerstone since June, 2013. Most of my time was spent running the front desk at the Salt Lake City office, but I am currently the Senior CSRD/Student Checkride Coordinator/VA SCO and rotate between both offices. My favorite part of working at Cornerstone is meeting new people and learning their stories. I love to watch students progress and go on to realize their dreams of flying. Outside of work, I love dancing, BTS music (K-Pop), trying new food, and spending time with my fantasic kids!
Education Coordinator
Stacie Whitford, Education Coordinator
My name is Stacie Whitford and I am the Education Coordinator for Cornerstone Aviation. I work mainly with our high school programs and the Liberty University students, but love working with any new student interested in flying. I have spent my live in the aviation industry. Both of my parents retired from the airlines and my husband flies for a Southwest. I hold a bachelors degree in aviation management and worked in several capacities for Skywest Airlines, including Infight Manager. I also spent time at United Airlines doing HR in Salt Lake City. I was the Aviation Admissions Counselor for Westminster College. I had the pleasure of joining the Cornerstone Aviation family in 2018 to continue doing what I love most…getting people into aviation!

Maddy Latham, CSRD
My name is Maddy Latham. I’ve lived most of my life in Syracuse UT and have always been fascinated by airplanes. When I was a Senior in High school my uncle took me up in his private airplane and I like to joke it was “love at first flight”! I knew this is what I wanted to do for the rest of my life. I am currently working at the front desk and saving up to get my Private Pilot’s License! In my spare time I love drawing, acting, and dancing around my kitchen.

Halley Mallory, Instructor
Meet Halley! She grew up in Georgia but came to Salt Lake for college and liked it so much she couldn’t bring herself to leave. Halley has been with Cornerstone since 2020 and loves the flying and the school. When she’s not doing something aviation related, you can probably find Halley enjoying food, funny tv shows, running, hiking, rock climbing, or sleeping.

Josie Rasmussen, CSRD
Hey, I’m Josie! I was born and raised outside of Chicago, IL and moved to Utah in August 2023 to begin flight training at Cornerstone. I’d been practicing as an athletic trainer for the past 10 years and decided to finally follow my passion for adventure and become a pilot. In my free time I enjoy hanging with my dog and cat, following sports, and getting into all of the activities that Utah has to offer.

Ann Mansell, CSRD
My name is Ann Mansell and I joined the Cornerstone team in October, 2022, as a Bookkeeper in the Accounting Department. While I myself am not a pilot or a student pilot, I have been around aviation for many years, and I enjoy flying with others as a passenger when I get the chance. I was a part of the Cornerstone Executive team, but moved over to the Customer Service side of the company in 2024. Outside of work, I enjoy spending time with my 4-legged kids, traveling, watching sports, and spending time in the sunshine.
