Working alongside a uniquely qualified team, Dr. Dominguez not only provides a superior level of healthcare for her patients at Health In Balance, but also serves on staff at Mission Hospital Regional Medical Center.


Dr. Dominguez completed BS in Kinesiology at UCLA, obtained her MD from UC San Diego, then completed her Family Medicine Residency at Long Beach Memorial Medical Center. As a resident, her passion for mothers and infants inspired her to complete additional training in Maternity Care.

Dr. Dominguez served as the Chief Resident for Obstetrics at Long Beach Memorial, delivering hundreds of babies and increasing her expertise in reproductive and hormonal health.

I am passionate about partnering with patients and customizing a scientifically based, health restorative medical program; their wellness being the best reward.
