    This was the third time one of my films was selected to screen at SEFF. Since it's so far away, I've only been able to attend in person once, but that one time, I felt so welcomed by the festival and its community partners all over Croatia. We were treated so well throughout the whole week, and I was introduced to such a beautiful part of Europe with so much nature and beauty. Definitely worth it! I wish I could have attended this year. Thank you SEFF for supporting my films over the years!
