About Alex
Alex supports patients as they navigate the intersection of mental health, hormones, relationships, and life's many transitions. She believes that meaningful psychiatric care begins with listening and that healing starts with feeling understood. Approaching each patient with compassion, curiosity, and respect, Alex considers it a privilege to be invited into each person's unique story. While she brings expertise in psychiatric care, she recognizes that her patients are the experts on their own lives. Together, they develop personalized treatment plans that align with what matters most to the patient, including their values, goals, and priorities.
Long before pursuing advanced practice psychiatry, Alex spent more than a decade supporting women and families as a registered nurse and an International Board Certified Lactation Consultant (IBCLC) in hospital, outpatient, and private practice settings. Caring for women during pregnancy, postpartum, breastfeeding, and other pivotal life transitions gave her a profound appreciation for the many ways hormones, relationships, and life experiences shape emotional health. Today, she continues to focus on caring for women across the reproductive lifespan, with specialized training in reproductive psychiatry, including perinatal psychiatry, perimenopause, menopause, and the emotional effects of hormonal change.
Alex is in the final semester of her Master of Science in Nursing program at Yale University, where she has maintained a 4.0 GPA while completing extensive psychiatric training in a variety of settings. Her experience includes a nine-month rotation at Johns Hopkins Suburban Hospital, where she trained alongside several psychiatrists in consult-liaison psychiatry, inpatient psychiatry, emergency psychiatry, and partial hospitalization. She also completed specialized training in reproductive psychiatry, providing integrative care across the reproductive lifespan with a particular emphasis on pregnancy, postpartum, and early parenthood. Alex is certified in Perinatal Mental Health (PMH-C) through Postpartum Support International and is currently pursuing certification as a Menopause Society Certified Practitioner (MSCP).
Naturally curious and committed to lifelong learning, Alex continually seeks opportunities to deepen her knowledge and refine her practice. In addition to her formal psychiatric training, she has completed advanced coursework in perinatal psychopharmacology, psychoanalytic psychotherapy, mindfulness-based cognitive therapy, trauma-informed care, and General Psychiatric Management for Borderline Personality Disorder. She is especially interested in emerging research exploring the connections among hormones, metabolism, inflammation, and women's mental health, and in translating new evidence into personalized, evidence-informed care.

​
-
Perinatal and postpartum mood and anxiety disorders

Alex joined Psychiatry for Women because she was seeking a physician-led, collaborative practice grounded in evidence-based care, mentorship, and a shared commitment to advancing women's mental health. She works closely with Dr. Julie Brownley through an intensive mentorship program focused on reproductive psychiatry, psychopharmacology, and the thoughtful integration of emerging evidence into clinical practice.
