At Infinity Health, our providers are more than medical professionals; they’re neighbors, mentors, listeners, and trusted partners in your health journey. Each one brings unique strengths, experiences, and heart to the care they deliver, especially in the rural communities we’re proud to serve.

We’re taking this opportunity to spotlight our dedicated providers who exemplify compassion, commitment, and excellence in everything they do.

Michael Black, NP 

Michael Black, NP, joined Infinity Health in 2021, continuing a lifelong commitment to serving his hometown community of Lamoni. His path into healthcare began as a first responder, where he discovered how meaningful it was to help people feel better during their most vulnerable moments. After completing his training at SWCC and Graceland University, Michael built his care philosophy around giving patients the time and space to genuinely share their concerns.

He loves the close-knit nature of rural healthcare, providing care close to home for the people who helped shape his own story. When he’s not in the clinic, Michael enjoys fishing, woodworking, and spending quality time with his wife and their two dogs. A proud Chiefs and Royals fan, he jokes that if he weren’t a provider, he’d be in his workshop full time, crafting something new.

Andrew Sullivan, PA-C

Since 2015, Leon native Andrew Sullivan, PA-C, has been caring for the very community that helped raise him. With degrees from Mercy College of Health Sciences and Des Moines University, Andrew chose family and general practice because it brings healthcare back to what matters most; helping people feel better and improving their quality of life.

Andrew appreciates the unique impact rural providers can make where outside resources may be limited. His approach to care is straightforward and patient-centered: understand what’s wrong and help people get back to feeling like themselves again. Outside of work, Andrew enjoys golfing, riding motorcycles, and exploring the outdoors.

Nate Allen, DO

Dr. Nate Allen joined Infinity Health in 2013 right out of residency, and he has been a steady, compassionate presence in our communities ever since. Growing up in Oskaloosa and later training at Des Moines University, Nate felt called to medicine as a practical way to help people and reflect kindness and compassion through his work.

For Nate, rural healthcare is deeply personal, built on relationships, trust, and walking alongside patients through both challenges and celebrations. He is grateful for teammates like his nurse, Darcie Moore, and for every opportunity to listen to a patient’s story and care for the whole person, not just their symptoms.

Outside the clinic, Nate enjoys life with his wife and four children. Whether camping, working on projects, or spending time with their Living Hope Church family, he finds joy in being outdoors and staying connected to those he loves. A self-described “terrible beekeeper,” Nate always finds something new to learn,  and approaches both hobbies and medicine with the same curiosity and heart.
