Full-service management, one client at a time.
Thirty years. Eighty-plus buildings. One promise: a dedicated team that knows your building, your board and your residents by name. That's the attention the big firms can't deliver.
Small buildings aren't a side business. They're the whole business.


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.
