Frances Hamman, DDS, MSD
Dr. Frances Hamman began her career in dentistry by earning her Doctor of Dental Surgery from Creighton University in 1991. Her passion for straightening smiles led her to continue on, earning her degree in orthodontics from Case Western Reserve University in Cleveland, Ohio in 1993. She has been a practicing orthodontist ever since.
Dr. Hamman’s interest in orthodontics began early -- she actually worked as a dental assistant in her father’s orthodontics practice all throughout high school, college, and dental school. In all, she’s got almost 30 years’ experience in the field. As she says, orthodontics isn’t just about creating a beautiful smile. It’s about helping patients enjoy teeth that function properly, too. When the teeth fit together like they should, the face has the proper proportion, and the simple acts of eating, speaking, and smiling are all easier… and more enjoyable, too.
In addition to her significant experience in orthodontics at home, Dr. Hamman had the honor of working for the U.S. Navy on active duty from 1997 to 2003. She was stationed in the United States Naval Academy, the Naval Hospital in Great Lakes, Illinois, and Yokosuka, Japan. She is proud to say she’s had the opportunity to treat smiles of all ages and with a range of orthodontic needs -- and she knows this experience has helped her become the successful orthodontist that she is today. For her exceptional work, she’s been recognized by Northern Virginia Magazine and the Washington Consumers Checkbook magazine as one of Washington’s Top Orthodontists.
To improve the alignment of patients’ smiles, Dr. Hamman first performs a clinical evaluation and uses advanced software to evaluate the patient’s teeth and unique bone structure. She partners with other dental professionals and surgeons as needed to help each patient achieve the very best results. Dr. Hamman also frequently engages in continuing education opportunities to stay up-to-date in the field of orthodontics.
Dr. Hamman has a full life outside of her work, too. She makes a point to balance life and orthodontics by traveling, learning new languages, and experiencing other cultures. She’s always active whether its art, photography, music, reading, water events, family activities, Dr Hamman enjoys just about everything the beauty of life has to offer.
