Who is the founder of the Corcoran group?

Could someone please clarify for me who exactly is the founder of the Corcoran group? I've heard a few different names mentioned in relation to this prominent organization, and I'm eager to learn the truth. Is there a specific individual who spearheaded the establishment of this group, or was it perhaps a collaborative effort among several key players? I'm particularly interested in understanding the background and motivations of the founder, as well as their vision for the group's future. Any insights or details you can provide would be greatly appreciated.
