   As Senior Talent Manager, my primary focus is executive search, where I drive the development of leadership teams across Mainsail’s portfolio companies. In addition to building these high-impact teams, I coordinate Mainsail\'s Leadership Acceleration Program (LEAP), aimed at investing in and advancing executive and manager-level talent across the portfolio. I also play a critical role in maintaining data integrity and optimizing systems to support our talent initiatives effectively.
