Sarah Kosasky Realtor

As Founding Partner and Manager of the Malibu office of Partners Trust— a brokerage that topped $2.5 billion in sales in 2016 alone, Sarah Kosasky demonstrates poise, expert knowledge, and a penchant for collaboration to all who perform under her leadership. Her vast strategic marketing background, coupled with her tenacious spirit, is instrumental in the continued growth and market position the Malibu office has achieved. Named 2015 Realtor of the Year by the Malibu Association of Realtors, Sarah is not only a leading force in Malibu real estate but continues to recruit elite talent, many of which are now top-performing associates in Partners Trust and Los Angeles. 
 
After graduating from The University of California at Davis, Sarah returned to Los Angeles to begin a career in advertising where she worked to develop successful campaigns for numerous Fortune 500 companies. In 2006, Sarah was hired by a privately owned real estate company as their marketing director, overseeing everything from corporate branding to website development.  As an entrepreneur with a love for learning and professional growth, Sarah got her broker’s license and parlayed her experience to later start her own brokerage in 2009, Arete Estates, which would be acquired by Partners Trust in the summer of 2014.

Sarah was the perfect Realtor for me. She was extremely knowledgeable, and helpful throughout the entire process. I was very nervous buying my first home, but Sarah made it quite enjoyable. She was patient with me, listened to what I wanted, and came through with flying colors. I couldn’t be happier with my home, which Sarah made sure to get for me at a great price. I highly recommend Sarah, you won’t be disappointed.
