JENNIFER CASEY, Director of Operations

Jennifer has had a long love affair with hotels beginning with a childhood stay at the grande dame Copley Plaza Hotel in Boston.

As a commercial real estate lawyer, she developed an expertise in resort and golf properties, working on trophy properties across the U.S., including La Quinta Resort & Club, PGA West, the Grand Wailea Resort and the Arizona Biltmore.

She manages talented design teams with a collaborative leadership style to deliver great design while meeting client budget and schedule goals. Jennifer is a LEED AP in commercial interiors. When not working, she can be found practicing Argentinian tango.

Dana’s career first began in Los Angeles in the fashion industry after graduating from the Fashion Institute of Design & Merchandising. Always passionate about interiors and design, Dana relocated to New York to further her career and landed at James Perse where she assisted in opening their Madison Avenue Flagship and an extension of the Soho location.  In this role she was inspired by the simple yet influential retail designs and the brand's identity of warm west-coast indoor/outdoor living architecture and interiors. Now back in California, Dana recently completed her second degree in Interior Design at FIDM. She values a space that tells a story and connects the individual to its design and the lifestyle it conveys. She has confidently discovered her aesthetic through fashion, travel (Melides, Portugal and Positano, Italy were favorites), and experiences living on both West and East Coast. 


Chloe received a Bachelor of Fine Arts degree from the School of the Art Institute of Chicago. Following graduation, Chloe took a position at the Children’s Hospital at the University of Illinois and found herself fascinated with the function of the physical spaces. Spending time within old buildings that had been retrofitted for modern use, but did not fully support their new purpose, ignited an interest in creating functional, beautiful spaces. A year and a half later, she moved back to her native Los Angeles to pursue a Master’s degree in Interior Architecture through Cal Poly Pomona. Chloe took her first leap into design working with an established, high-end residential designer. She then went on to hold the role of Resource Librarian at Hirsch Bedner Associates, where she collaborated with the entire design staff on luxury hospitality projects. From there, Chloe took a design role with Studio HBA, where she worked on branded and boutique hospitality projects.
