Our Story

Purposeful.

Practical.

Personal.

Founded by attorneys Blake A. Rosenberg and Heather C. Parker, Manor Law Group was built to offer something different: a legal experience that’s personal, responsive, and grounded in real-world results.


Heather and Blake each had thriving practices, but they knew they could serve the community better together. After forming Rosenberg & Parker, LLC in 2016, they quickly became a go-to real estate firm in Naperville for agents, brokers, and families seeking smooth closings, honest guidance, and practical estate planning. As the team expanded, so did the firm’s services—growing into what is now Manor Law Group. That growth has allowed them to support clients in business matters, probate, and comprehensive estate planning, all with the same focus on accessibility, communication, and client care.


Today, Manor Law Group serves clients across Northern Illinois, combining deep local knowledge with a commitment to making legal services feel more human.
