Dr. Margaret Johnston is originally from New Jersey, but has lived in the Northern Virginia area for many years. She holds an undergraduate and M.A. degree from the Catholic University of America and formerly taught high school level French in Alexandria, Virginia. In 1982, Dr. Johnston obtained her Doctor of Optometry degree from Pennsylvania College of Optometry and has been in optometric practice ever since. She previously had her own practice in Springfield, VA for many years, but now enjoys practicing part time. This allows her to engage in another passion: She has authored the award-winning book: "Faith Beyond Belief" (www.faithbeyondbeliefbook.com) and is hard at work on a second book. Dr. Johnston is the mother of two grown son and lives with her husband in McLean, Virginia.
