Dr. Mullen


  • Obstetrics
  • Family Medicine

Family Medicine is a specialty area of Medical Practice which encompasses the entire family in a special way of practicing medicine.  Instead of offering fragmented health care, as most specialty medical practices do, Family Medicine offers total family, holistic health care.  This means that you can see your Family Doctor for Obstetric care (delivering your baby at JCHC), Pediatric Care (at the Family Medical Center in Buffalo or Kaycee),  General family wellness check ups, Gynecology (well women checkups), and Geriatric care all in one place, with one doctor who knows you well.

Family Medicine offers a unique, comprehensive high quality health care experience that other specialties simply can't offer.

Lisa Mullen always wanted to be a doctor.

While growing up in Newcastle, Wyoming, she had a great connection with her Family doctor. That close connection and the personal relationship that we forged with our doctor “solidified my decision to go into Family Practice Medicine.”

Dr. Mullen really likes women’s health and children’s medicine.

" In medical school, I realized that
I love delivering babies and caring for families.
It really is what Family Medicine is all about.
I love to be part of the special events in people’s lives."

Dr. Mullen and her husband were looking for a small close knit community to raise their family, and Buffalo was just what they were looking for.   Dr. Mullen is married to Louie who is in the newspaper business. They are raising their daughter in Buffalo.

Dr. Mullen loves to read, bake and spend time with her family.
