Osceola Medical Center's Clinicians Named to Prestigious "Top Doctors" List

(Osceola, WI—September 11, 2026) Minnesota Monthly magazine has recognized three of Osceola Medical Center’s clinicians in its 2026 list of Top Doctors: Chief Medical Officer, David Frenz, Dermatologist Mohiba Tareen, and Allergist Nancy Ott.

Each year, Minnesota Monthly identifies the state’s leading doctors based on insight from those who know medicine best: physicians themselves. Doctors across Minnesota were asked to nominate colleagues based on their answer to the question, “If you or a loved one needed medical care, which doctor would you recommend?” The most-nominated individuals in each specialty earned a place on the annual list.

“Being named to this list is particularly gratifying because nominations come from my peers,” said Dr. Frenz. “I’m honored to be considered someone they’d recommend to people they care about.”

“This recognition shows OMC’s commitment to providing the communities we serve with exceptional care, close to home,” said Kelly Macken-Marble, CEO of Osceola Medical Center. “Having Dr. Frenz on staff means that we can provide Osceola and surrounding communities with mental health and addiction care; Dr. Tareen allows us to offer excellent skin care services, and Dr. Ott brings her decades of expertise in allergy and asthma care.”
