Simplifying the Path to Coverage — and the Care That Follows.

Denise Kajanoff

Chief Executive Officer

Denise is driven by one goal: making sure people get the coverage they’ve earned, the care they deserve, and real access to the resources that help them navigate a complicated healthcare system. She believes in surrounding people with the right resources and being part of the effort to help the most vulnerable gain access to high-quality, affordable care.

She spent over a decade at Optum and UnitedHealthcare, helping build the nation’s largest payment integrity organization and leading growth across Optum and UHC’s Employer and Individual, Military and Veterans, Medicaid, and Medicare businesses — work that led to her selection for UHC’s Executive Development Program at Stanford, and, more recently, recognition from the University of Phoenix as one of 76 leaders selected from a pool of more than one million for healthcare industry leadership.

She’s also a longtime community advocate, giving her time to organizations like PROVAIL — dedicated to ensuring people living with disabilities can live life on their own terms. She spent more than a decade on PROVAIL’s board, including as its first woman board chair, and has chaired the American Heart Association’s Circle of Red. After UHG, she built Cityblock Health’s Partner Success function, led behavioral health products at Evernorth (Cigna), and advised other healthcare startups working toward the same kind of change. Today she’s also the Washington Market President of Together Health, a primary care organization that serves communities and employers directly.

Tonya Copeland

Chief Operating Officer

Tonya has spent her career inside the exact populations and programs Determined Care serves: 14 years with Evergreen Life Services across home health, home care, and long-term services and supports, then senior leadership at UnitedHealthcare Tennessee as Vice President of Clinical Services for Complex Populations and Executive Director.

She went on to Managing Principal at Health Management Associates and Chief Growth Officer at Liberty Healthcare Corporation, where her work in IDD and LTSS assessment mirrors the functional-impairment documentation Determined Care builds today. A published author on the needs of individuals with intellectual and developmental disabilities and co-occurring mental health conditions, she also advises healthcare startups and growth-stage companies on Medicaid strategy — helping translate mission-driven ideas into sustainable businesses.

Melissa Reilly

Chief Strategy Officer

Melissa brings more than two decades of experience driving growth, innovation, and transformation across behavioral health, payer strategy, and healthcare delivery. Her career spans senior leadership roles at UnitedHealth Group, Aetna, and Evernorth Behavioral Health, where she served as Chief Growth Officer, leading enterprise strategy and business development to expand access to high-quality mental health care.

Melissa also founded STLTH CNSLTNG, an advisory practice focused on elevating healthcare startups, which she continues to lead alongside her role as Chief Strategy Officer at Determined Care. She holds a JD/MBA from Quinnipiac University.

Anna Hardeman

Chief Growth Officer

Anna’s growth career runs through the exact motion Determined Care’s go-to-market depends on: selling into health plans and state programs. She spent her early healthcare years at Optum advancing from Senior Analyst to Senior Consultant, then led product at Level2 before moving into Medicaid business development leadership as Director of Strategy & Solutions at UnitedHealthcare Community & State, then Managing Consultant at Bullard Advisory Group.

She went on to Director of National Payer Sales at Kinetik and, most recently, growth leadership at Thrive Mobile. Anna holds a BA in Political Science and International Relations from St. Catherine University, sits on the board of the Non-Emergency Medical Transportation Accreditation Commission (NEMTAC), and is a member of Women Business Leaders of the U.S. Health Care Industry.
