ADK Advisory

ADK Advisory helps nonprofits and philanthropic foundations strengthen their operations, manage risk, and build the infrastructure they need to make a lasting impact.

Founded by Rachel Arkus, the firm provides embedded fractional executive leadership and hands-on consulting tailored to each organization’s needs. From improving internal systems and reducing administrative bottlenecks to managing major donor pipelines and securing unrestricted funding, ADK Advisory helps mission-driven teams get the support they need without the cost of a full-time executive hire.

With more than 20 years of experience, Rachel understands the challenges nonprofits face when they're expected to do more with less. She previously managed a $20 million operating budget, helped grow a national team fivefold, and built major funding pipelines.

ADK Advisory goes beyond recommendations and generic training. Rachel works alongside leadership teams to turn ideas into practical solutions that last.

Through Ops4Good, the firm also partners with philanthropic foundations to strengthen their grantee organizations by providing operational support at no cost to the nonprofits themselves.
