About

Im dedicated to delivering a refined, client-focused real estate experience built on trust, communication, and exceptional service. From first-time buyers to sellers looking to maximize their homes value, I approach every transaction with professionalism, strategy, and attention to detail. Serving clients across a variety of price points including the highly active $300K market I believe every client deserves concierge-level service, strong advocacy, and a seamless experience. My goal is not just to close transactions, but to build long-term relationships that lead to confidence, repeat business, and referrals.

About

I have been, and will always be, a marketing rebel .Helping homeowners in the upper bracket find or sell their Luxury Lifestyle Home is where my expertise shines. Perhaps due to my strong will, the meaning of the word no has never held any fascination for me. I figure if I roll up my sleeves and work harder, I will get the job done.

About

Raised in Northern California, I developed a strong foundation rooted in hard work, ethics, and communityprinciples that continue to shape my approach to real estate today. Dual-licensed in California and Illinois, I bring a wealth of local knowledge and global connections to every transaction. Coming from a highly competitive family of professional athletes, I am a former state-ranked tennis player, a lifelong equestrian, a runner, and a swimmer. This natural energy and enthusiasm drive my commitment to excellence, whether you are selling your first home, searching for a dream residence, or exploring investment opportunities. I am also deeply committed to giving back to the communities where I work and reside. My past volunteer work includes serving on the Board of Directors for STAND (Battered Womens Alternative) and supporting local food banks, women's shelters, and children's hospitals.
