Diane Maistros is an execution focused fractional operations leader who partners with growing behavioral health and human services nonprofits when strategy is clear—but the organization’s systems, roles, and operating rhythms haven’t yet scaled to support the next level of growth. She has led major mergers, multi site integrations, and enterprise restructurings across complex nonprofit environments. Through the ARTEMAI™ Resilience Architecture Diagnostic and structured fractional leadership, her work stabilizes core infrastructure, builds leadership depth beneath the Executive Director, and reduces systemic over-reliance on the top seat.

Founded in 2026, Artemai Solutions was created to help nonprofit organizations strengthen the operational foundations required for long-term resilience.
After decades of executive leadership in behavioral health and human services, founder Diane Maistros saw a consistent challenge across the sector: organizations with powerful missions often lacked the leadership infrastructure and operational systems needed to sustain growth and navigate change.
Artemai Solutions was built to close that gap—providing strategic diagnostics and fractional executive leadership that stabilize operations, strengthen leadership capacity, and position nonprofits for durable impact.

Testimonials
Testimonials
- ”Having had the privilege of working with Diane in an operational leadership capacity, I experienced her significant contributions as a leader. Diane is a value-based leader with executive-level insights into both the operational and human resource needs of the organization. She is a collaborative leader, an organized and deep thinker and uses technology effectively to drive efficiency... She demonstrates an intellectual curiosity that will make her an asset to organizations seeking fractional leadership to bridge transitions.” - Marina Cecchini, Behavioral Health Leader, Sheppard Pratt
- “I found Diane to be extremely competent and knowledgeable. She has overseen at the executive level HR, Payroll, IT, facilities and maintenance, and transportation management. She is also well-versed in board and organizational development. While she can address any of these areas individually, her real strength is in improving their integration with one another to maximize both efficiency and quality, and to support an organization's mission and goals. She is a master at analyzing systems but is also very detail oriented and will provide concrete steps to your leadership team for their consideration. You will not regret bringing Diane in to assist with your organization's advancement.” - Lori Doyle - retired, Lobbyist for CBH; and former COO, Mosaic Community Services
