Gary A. Aisenbrey


As a board-¬certified obstetrician-gynecologist with certification in maternal-¬fetal medicine, it has been my pleasure to provide special care for women during their pregnancies. There’s no greater personal reward than working together to achieve the best possible outcome for you and your baby.

I look forward to meeting you and helping you have the smoothest, most rewarding pregnancy possible.

Gary M. Joffe


Growing up in a small town in New Mexico, I was inspired to pursue a career in maternal and fetal medicine by the caring local obstetricians I worked with in high school and college, and by my mentors at the University of New Mexico – Dr. Gary Aisenbrey and Dr. Kent Argubright.

Thank you for allowing us to share in your prenatal care. I look forward to meeting you!
