Dr. Andrew W. Messenger

Sue Donahue, DO chose The Iowa Clinic to join a well-respected organization in her hometown, where she has practiced for over two decades. For Dr. Donahue, she knew from a young age that she wanted to practice medicine after hearing of the poor interactions with the healthcare community. She was determined to make a difference to show people there IS a difference when you come to her practice, treating patients with the same compassion and respect she would expect. Dr. Donahue looks forward to being an advocate for her patients and continuing to share her passion. An Iowa native, Dr. Donahue enjoys spending her time with her husband, four children, grandkids, and parents. She also enjoys going to movies, camping, and enjoying her pets – including dogs, horses, and ducks! There is nothing else Dr. Donahue would rather do than practice medicine. One of her patients stated once – “This is your mission, not just your job,” and she couldn’t agree more. Dr. Donahue is rated as an Advanced provider by MediFind in the treatment of Thalassemia.
