About Us

Since 2010, the Vitae Clinic has held a higher standard of care for our patients in all aspects of obstetrics, infertility, and gynecology with respect and value of life. The Vitae clinic is a truly unique private office where your gynecological and obstetric care is our highest privilege. We are here to care for patients from adolescence through menopause with a level of care and commitment you may have never experienced before. At the Vitae Clinic, our sincerest hope is to nurture a relationship of care with each patient that will last a lifetime

We serve the needs of women through NaProTECHNOLOGY®. This comprehensive system was developed through extensive research at the National Center for Women’s Health. It provides the best in current medical care, applying diagnostic and therapeutic techniques in a way that is cooperative with the natural functions of a woman’s body. It can be used to treat a wide range of gynecologic problems including premenstrual tension syndrome, ovarian cysts, abnormal bleeding, irregular cycles and recurrent miscarriages.
Since its creation in 1976, NaProTECHNOLOGY® has helped thousands of women and couples achieve their family planning goals.

The successes of these innovations have inspired us to create an office where we can provide top tier health care while still staying true to our faith- based ethics and devotion to high standards of medical and surgical practice. Therefore, we do not provide oral or other artificial contraceptives, provide or refer for abortions, or use methods of achieving pregnancy that contradict these directives.
