Our Mission

At Four Corners OB/GYN, our mission is to provide exceptional, all-inclusive women’s healthcare with a focus on personalized, evidence-based practices for women in adolescence through midlife and beyond. We prioritize their well-being by offering a full spectrum of services, including wellness exams, obstetrics, and surgeries, all delivered by a team of skilled and compassionate providers.

Our Vision

Four Corners OB/GYN believes everyone, irrespective of age or gender identity, should experience comprehensive and personalized healthcare that empowers them to lead fulfilling and healthy lives.

"I have seen several doctors and practitioners at Four Corners OB/GYN over the years and have felt comfortable and cared for by each and every one of them. I have a history of trauma so it’s important to me to feel super safe and comfortable. I always recommend Four Corners when people ask me for referrals and everyone I have sent there has thanked me for the recommendation because they too have felt so cared for!"

C. Dickinson

“Every nurse and doctor who ever attended to me was knowledgeable, professional, and compassionate. I felt comfortable asking questions and expressing concerns. I highly recommend this office to all expecting mothers.”


“I have a daughter with a severe disability. This practice was amazing to work with. Turned out my daughter needed a surgery. The team, their accommodations and professionalism were A+. Our surgeon visited with us before, during and after the procedure. He checked in and really showed how much he cared about her. Everything went great. We couldn’t be happier.”


“I am incredibly grateful for the compassionate and exceptional care provided by the Physicians, PAs, and NPs at Four Corners. From my prenatal care to the beautiful delivery of my son by Dr. Lasich, every aspect of the care provided has been professional and empathetic. Dr. Berarducci provided incredible care throughout most of my complicated pregnancy. I had many questions and concerns during my pregnancy, but always felt well informed and supported by all of the providers. I am forever grateful to have such an exceptional OB group in our small community.”
