Fifteen years and a designer's eye for the homes that rarely reach the market.
Vesper House was founded on a simple conviction: that a significant home deserves one accountable advisor with genuine design fluency — not a machine.
Founder & Principal Broker
After a decade advising private clients at two of the city's largest brokerages, Sienna founded Vesper House in 2011 to practice real estate the way she believed it should be done — personally, patiently, and without compromise.
She personally handles every mandate she accepts, capping her roster so that each client receives her full attention. The result is a practice built almost entirely on referral and repeat business.
- Licensed Principal Broker
- Certified Luxury Specialist
- Accredited Buyer’s Rep.
Discretion is a service, not a slogan.
We believe the best transactions are quiet ones. Many of our sales never appear on a public portal; they move through a trusted, confidential network of qualified buyers and their advisors. For our clients, that means privacy, control, and a process that protects both their home and their time.

What clients say
Sienna is the rare advisor who tells you what you need to hear, not what you want to hear. We trusted her completely.
Three transactions over eight years. I would not use anyone else.
Calm, precise, and relentlessly prepared. She made a complex sale feel effortless.
