Leadership

The principals are the practice.

Sandberg Management Corp. was founded in 1994 by Louis Sandberg, who built the firm from the ground up with a singular focus on boutique residential communities. Marsha Kolker joined in 2003 and today serves as co-owner and CEO, leading the company's growth and day-to-day operations.

Together they built a firm around small and mid-sized buildings, many of them Landmark or Historic. High expectations. No margin for error. Hire Sandberg and you get the people whose name is on the door.
