She spent 16 years as a Managing Director and product specialist at a renowned financial institution.

Nowadays, Sarah resides in Big Sky, Montana, alongside her husband, two kids, and beloved pup, Lou.

In The Press

“…Visual interest is going to help make this chair sing and bring the room to life. Look for an attractive silhouette, an interesting texture, or patterned fabric, all of which play into the overall look of the piece. Chairs are a great and less expensive way to turn up the volume in a room.”
