I'm Theresa N., the breeder behind Abberann Glens located in Saint Charles, IL. I am an Obstetrician-Gynecologist with specialty training in genetics and maternal-fetal medicine. Although I have retired from an active medical practice, I remain very involved with women’s wellness and teach around the world. My program emphasizes the preservation of the Glen of Imaal Terriers - a rare breed that has existed in seclusion for many years.
