About James
I was two classes away from becoming a nurse. That decision changed everything.
"I got into nursing because I wanted to be there for people when they needed it most. Turns out — real estate is exactly the same thing."
What drew me to medicine was the same thing that makes me great at real estate: showing up for someone during one of the most stressful moments of their life and making it feel manageable. I gave myself one year to make it work. I never looked back.
My background in economics means I don't just know homes — I understand markets, data, and where things are headed. I'm not here to sell you something. I'm here to help you make one of the best decisions of your life.
