Alexandra Luevano needed glasses. Optometrist Gregory Johnson, a nondenominational Christian who works at Virginia Vision Therapy, was looking for ways he could volunteer. When Johnson learned that Luevano, his new patient, was the program director of Catholic Charities Mother of Mercy Free Medical Clinic, he realized his prayers had been answered. “God did the rest,” said Luevano. Less than a year after Johnson and Luevano met, the Mother of Mercy clinic in Woodbridge began offering in-house eye care for clinic patients.
