Doctors in the West Valley

Dr. Sabre's path to women's health started on the East Coast and wound through some unexpected places. After studying biology at Drexel University, he headed to Guadalajara, Mexico for medical school, and it was during clinical rotations that brought him to Phoenix where he first realized OB/GYN was where he belonged. He returned east to complete his residency at Lincoln Hospital in the Bronx, one of New York City's busiest safety-net hospitals, where managing a high volume of both routine and high-risk pregnancies became second nature. The experience sharpened his skills across the full spectrum of obstetrics and gynecologic surgery, with a particular focus on minimally invasive techniques. Dr. Sabre is also a dedicated researcher, with multiple peer-reviewed publications and presentations at national conferences. His research earned him the SOGH Inaugural Future Leaders Award and a CIR Patient Care Trust Fund Research Grant, recognition of the kind of curiosity that keeps him pushing for better outcomes. Now at MomDoc, he's excited to bring that blend of surgical skill, academic rigor, and hands-on clinical instinct to the women of the Valley.

Before Dr. Shaw ever set foot in a medical school, she was running calls as a volunteer paramedic with the Fredericksburg Rescue Squad and teaching math and science to middle schoolers. Both roles shaped the physician she would become: someone who stays calm under pressure and knows how to explain complicated things in plain language. She studied mathematics and biology at Mary Washington College, earned her MD from Eastern Virginia Medical School, and completed her OB/GYN residency at Temple University Hospital in Philadelphia, where she served as Administrative Chief Resident. Her research on thrombophilia-related pregnancy loss and paternal ethnicity as a preeclampsia risk factor has been published in two of the field's leading journals. In Arizona, Dr. Shaw has become a physician leader, steadily taking on roles that let her improve care not just for her own patients but across entire hospital systems. In January 2026, she began a two-year term as Chief of Staff at Banner Ironwood Medical Center, and she chairs MomDoc's Quality Assurance Committee. Through it all, she remains a clinician first, still energized by the daily work of guiding women through pregnancy and gynecologic care.

Dr. Sta. Maria's path to medicine started in the research lab. As an undergraduate at SUNY Stony Brook, she fell in love with the precision of biochemistry, but it was the human side of science that ultimately called her to clinical work. She headed to New York University School of Medicine, then completed her OB/GYN training at Long Island Jewish Medical Center and Albert Einstein College of Medicine, where she was named Chief Resident. After more than two decades practicing in Arizona, Dr. Sta. Maria has built a reputation as a physician who takes time to listen, tailoring her approach to each patient rather than defaulting to a one-size-fits-all plan. She describes herself as someone who finds deep satisfaction in the full spectrum of women's health, from guiding a first-time mother through pregnancy to helping a patient navigate complex gynecologic care.

Liz grew up in Boise, Idaho, and made her way to Utah for her undergraduate years at BYU, where she studied public health and discovered a love for the intersection of patient education and hands-on care. Before PA school, she worked as a Medical Assistant and eventually Lead Medical Assistant at a family medicine clinic, and she served as an Anatomy Lab Teaching Assistant at BYU. Those experiences confirmed what she already suspected: she wanted to be in the room with patients, not behind a desk. Liz completed her PA training at Midwestern University in Glendale, rotating through specialties ranging from emergency medicine to maternal-fetal medicine. It was her women's health rotations that sealed the deal. She was drawn to the way OB/GYN care lets her walk alongside women through every stage of life, from first prenatal visits to well-woman care and everything in between.

Luba's career in women's health began an ocean away. She trained across some of England's most respected hospitals, orthopedic nursing at the Nuffield Centre in Oxford, her registered nurse qualification at the Royal Free in London, and her midwifery certification at Northwick Park in Middlesex. Each stop added a new dimension to her clinical skill, but it was midwifery that captured her fully. In the early 1980s, Luba made the leap to Arizona and earned her American certification through the College of Nurse-Midwives. More than three decades later, she has built a practice that spans the full arc of women's health, from prenatal care and family planning to hormone therapy and menopausal management. Perhaps the best measure of Luba's impact is the loyalty she inspires. Many of her patients have followed her from practice to practice over the years, some through multiple pregnancies and into the next chapter of their health. That kind of trust is not earned with credentials alone; it comes from showing up for people consistently, year after year, and treating each visit as if it matters. Because to Luba, it does.

Ashlee calls herself a true Arizona girl, but her path to MomDoc took a detour through Charlottesville, Virginia first. She played Division I softball at the University of Virginia on a full scholarship, earning her degree in American Studies before returning home to Arizona. The discipline and teamwork she learned as a college athlete carried right into her nursing career, she earned her BSN at Arizona State University and then jumped into some of the most high-pressure settings in medicine, working as an emergency room RN at Banner Desert Medical Center and in the cardiac cath lab at Southwest Cardiovascular Associates. But it was during her Family Nurse Practitioner training at Herzing University that everything came together. Ashlee rotated at MomDoc with Alicia Kimura, FNP, and within weeks knew that women's health was where she was meant to be. She brings the intensity of someone who has worked codes and cardiac emergencies, combined with the warmth and connection that women's health demands. That blend, calm under pressure, deeply relational, is what makes her a natural fit.
