Our Physicians

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. Evaluating difficult pregnancies and formulating a compassionate, well-researched treatment plan is a true privilege. There’s no greater personal reward than working together to achieve the best possible outcome for you and your baby. At Perinatal Associates of New Mexico you can expect the most comprehensive evaluation and care. Our practice has four maternal-¬fetal medicine specialists that bring more than 75 collective years of experience addressing obstetric problems.

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. After completing my fellowship in Maternal and Fetal Medicine at UNM, I joined Perinatal Associates of New Mexico in 1999.

At PANM, we are committed to providing you the highest quality care and delivering this service with a personal touch. We are blessed to have a staff that really takes the time to get to know you while providing the best service available in the Southwest.

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

Michael S. Ruma


As a board–certified maternal–fetal medicine specialist, my top priority is caring for patients with a high–risk pregnancy. Helping women overcome medical, surgical, or obstetrical problems with optimal care during their pregnancy is a great joy for me. I joined Perinatal Associates of New Mexico in 2008 after completing my fellowship training in Maternal–Fetal Medicine at the University of North Carolina. A native of Omaha, Neb., I received my MD from Creighton University School of Medicine and stayed at Creighton to complete my residency in Obstetrics and Gynecology.

Please let me know if there is anything I can do to improve your care while you’re with us at Perinatal Associates of New Mexico. I look forward to meeting you!

I spent five years after residency training as an obstetrician and gynecologist; I split that time between Alaska and New Mexico. During those years I delivered many babies, won numerous teaching awards and discovered an interest in caring for women with high risk pregnancies. Helping women and their families deal with the complexities and problems that can affect pregnancy is my top priority. I joined PANM in January 2013 after completing my fellowship training in MFM at the University of New Mexico.

I am always available and seeking ways to improve our care.

Our Staff


Announcing the retirement of Dr. Kent Argubright

With warm wishes, Perinatal Associates of New Mexico announces the retirement of Kent F. Argubright, MD.

After completing his medical degree at Saint Louis University, Dr. Argubright traveled to the University of New Mexico for his internship and residency in obstetrics and gynecology and remained there to pursue his maternal-fetal medicine fellowship training. He practiced at the University of New Mexico as an assistant professor until 1987, when he founded Perinatal Associates of New Mexico, the first independent, private maternal-fetal medicine practice in the state. Over the last three decades, Dr. Argubright has stood as an esteemed maternal-fetal medicine physician to patients and referring providers alike throughout the great state of New Mexico.

He has served on innumerable committees and appointed to many boards at the UNM School of Medicine,UNM Hospital, the State of New Mexico, Presbyterian Hospital and Healthcare Services, AlbuquerqueObstetrical and Gynecological Society, Mountain States Regional Genetics Services Network, AmericanAcademy of Pediatrics, and American College of Obstetricians and Gynecologists. During his esteemed career, he published numerous peer-reviewed manuscripts on topics such as expectant management of severe preeclampsia to nutritional supplementation during pregnancy and presented hundreds of academic lectures and research presentations locally, regionally and nationally.

From the beginning of his medical career, his driving goal centered on helping women and their families no matter how complicated their pregnancy may become. He has benefited countless numbers of patients and their families over more than 30 years as a practicing perinatologist. He undoubtedly has achieved his goal and thousands of children, now both young and old, can attribute a hand in their well-being to his care during their mother’s pregnancy. We remain indebted to his vision and relentless commitment to his practice, propelling Perinatal Associates of New Mexico from a single office in Albuquerque with a few employees to now 10 offices throughout the state with over 130 team members assuring our success today and into the future. Dr. Kent F. Argubright will be greatly missed by his patients, colleagues and staff.

Perinatal Associates of New Mexico congratulates Dr. Argubright as he begins his retirement and moves on to write his next chapter traveling and spending time with his adoring family.

We appreciate the trust you place in us when referring patients and will continue to provide the same level of care you have grown to know us for at Perinatal Associates of New Mexico.
