Elevating your wellness

Dr. Pero was born and raised in Baton Rouge, Louisiana, and comes from a long lineage of accomplished, well-respected physicians. Surrounded by strong, supportive women throughout her life, she naturally gravitated toward medicine and developed a deep passion for women’s healthcare, ultimately specializing in Obstetrics and Gynecology.

During her own infertility journey with her husband, Dr. Pero was diagnosed with Endometriosis, Uterine Fibroids, Hormone Imbalance, and Idiopathic Thrombocytopenic Purpura — none of which “ran in her family.” This pivotal moment led her to recognize the limitations of relying solely on Western Medicine, while discovering the powerful advantages of Integrative, Lifestyle, and Functional Medicine.

After incorporating targeted nutrition, supplements, acupuncture, and whole-body support alongside modern fertility treatments, she was able to conceive. She and her husband went on to have three biological children and adopted their fourth. By embracing a Functional Medicine lifestyle through personalized nutrition and supplementation, regular movement, sleep, and stress optimization, and other foundational pillars of health, she has remained symptom-free from Endometriosis and Uterine Fibroids without surgical intervention or hormone therapy. 

Through her own health journey, she offers understanding and guidance, and is excited to help you realize your full health potential and live your best life yet.
