Tiffany Antheaume

Interior Designer Partner


Tiffany was born and raised in Las Vegas.  After receiving her BA in Interior Architecture she did what any native who grew up around hotels and casinos would do and pursued her career in Hospitality Design.  While she enjoyed designing high end suites, restaurants and lounges she craved personal connections with her clients.  For the last 15 years she has immersed herself in residential projects, helping clients through all aspects of the design process.  She creates modern spaces with intimate details, carefully uncovering the clients desires and making them come to life. Her favorite things: adding whimsical elements, finding the perfect light fixtures, and creating lasting relationships with her clients.

Amanda Thomas

Interior Designer Partner


Amanda began her professional design career in floral and event design including many televised weddings.  Ultimately choosing to curate spaces that could be enjoyed everyday, she pursued an education in Interior Design. Working on both residential and commercial projects, she consistently strives to create environments where her clients can shine whether it be in business, entertaining or finding serenity.

Amanda recently returned to Las Vegas and continues to enjoy marrying styles of couples with varied tastes as her favorite challenge. In Southern California and Arizona, she worked in luxury communities including Newport Beach, San Clemente, Scottsdale and Paradise Valley.  Her favorite things: wallpaper, modern and historic homes, and remodeling her clients’ beloved homes to give them a fresh aesthetic.
