It's National Women Physicians Day! In 1821, Elizabeth Blackwell was born, and she later became the first woman in the United States to earn a medical degree, graduating from Geneva Medical College in 1849. Now, her birthday, Feb. 3, is celebrated as National Women Physicians Day to honor Blackwell and others like her who have paved the way for countless women in medicine today. They helped increase diversity, decrease pay gaps and address other pressing challenges in a field that was once male dominated.

Today, we honor and celebrate Dr. Alexandra Matthews, Sports Medicine specialist with Orthopedic Performance Institute who is dedicated to providing excellent care to every patient.
