Sharki Kontra // Accountant / Organisateur

For as long as Sharki can remember she’s had dreams of soaring in the air. Becoming a pilot after high school was not an option nor encouraged. Instead Sharki put herself through college, started a career that allowed travel, had children and the idea of being a pilot seem more unattainable. After a Discovery Flight at Ponderosa Aero Club, she realized that she was happiest in the air and secretly obtained her private pilot license in 2011. She began living her dream and discovered her passion. Sharki has an instrument rating, commercial multi-engine land, commercial single-engine land and single-engine seaplane certificates, flies tailwheel aircraft, has complex and high performance endorsements, and is always improving her backcountry skills. She has a ground school instructor certificate and landed a part-time job flying a PC-12. Sharki is an accountant and works at Ponderosa managing the accounting system, assisting the manager, coordinating some of the club’s events and social activities, and being a liaison with various aviation organizations. Sharki hopes to inspire others to find their passion and follow their dreams.

Preston has been working at Ponderosa since September 2018 and plans to start flight training in June 2019. Aviation is his calling and he has found his home at Ponderosa.
