About
JamesKastner-20250320-004-warm.jpg

Since 2002...

...my name has become synonymous with marketing innovation and strategic thinking. My career took off in San Francisco, first at Zephyr on 17th Street and later Paragon Real Estate Group, where I was a key player on a top-performing team. I made a splash by creating the city's first property website using basic HTML in 2002, setting the stage for a series of industry firsts, including custom CMAs and professionally printed marketing collateral such as value point signs and multi-page brochures. I have continued to lead the way with high-quality marketing materials, consistently setting a new bar for the industry.

"James' mind works at another level from the rest of us humans."
