Victoria Brueggert PMHNP, PMH-C

Victoria Brueggert APRN

Victoria (Tori) Brueggert is a Nurse Practitioner board certified in Adult Primary Care along with Psychiatric Mental Health. After initially working in medicine, she found a love of psychiatry which pushed her to pursue her certification in mental health. Tori has a laid back and holistic approach with her patients. She often refers her patients to participate in psychotherapy in order to get the best long-lasting results for her patients. Tori also has a specialty in Perinatal Mental Health. After her own battles postpartum, she decided to get certified to care for patients of childbearing age through pregnancy and postpartum. She has also completed a Fellowship in Reproductive and Integrative Psychiatry and uses natural and holistic treatments in addition to medication.

When she is not with patients, Tori likes to enjoy her young family, loves the outdoors, and is a Peloton enthusiast. 

Sarah Bier

Sarah Bier APRN

Sarah became interested in pregnancy care after falling in love with the midwifery model of care when she was pregnant with her first of three children. She became a doula and entered University of Illinois at Chicago's accelerated nursing program in 2014 to become a nurse midwife. Sarah graduated in 2017 and has provided holistic, comprehensive, and client-centered reproductive physical health services and mental health care in a variety of settings in Chicago. She was a member of the first cohort to acquire certification in perinatal mental health care by Postpartum Support International in 2018. While working in private practice and in low resource, high need communities, Sarah became frustrated with the silo-ed nature of health care and the barriers clients experienced trying to obtain high quality mental health care. She returned to school to become a psychiatric mental health nurse practitioner through Frontier Nursing University with the goal of providing more expansive mental health services to people of reproductive age. She strongly believes in centering client goals, trauma informed care, and using a strengths-based approach.

When not working, Sarah loves doing crossfit, going for walks in the woods, baking, gardening and pottery. She and her family live a modern homesteading life on Chicago's northside with a dog and 3 cats (and a slew of hens and a colony of bees live in the garden).

Amanda Hahn PMHNP, PMH-C

Mandy Hahn APRN

Amanda (Mandy) knew she was passionate about pregnancy from a young age. A bit of a nerd in high school, she would go to the library and check out all the books she could find about pregnancy (and gave her mother a heart attack when she found them in the closet and had to ask, "Mandy, is there something you need to tell me??"). After working in Labor and Delivery as a nurse, she was quickly disappointed with some of the care she witnessed. She went back to school and began working as a Certified Nurse Midwife in Rockford, Illinois.


While working with a high risk, under-served population, she became frustrated with the lack of mental health care options available to her patients. She went back to school again, where she graduated in 2020 as a Psychiatric Mental Health Nurse Practitioner. Wanting to combine her passion for both Midwifery and Psychiatry, she received additional training and certification in Perinatal Mental Health.


She started Dahlia Center to provide this specialty care to improve outcomes for both her patients and their families. Mandy strongly believes in collaborative, trauma informed, patient-centered care. Because of her intimate knowledge of pregnancy, birth, and postpartum, as well as her specialized training in perinatal mental health, she is able to offer a unique perspective and treatment experience. She has also completed a Fellowship in Reproductive and Integrative Psychiatry and uses natural and holistic treatments in addition to medication.

When she's not working, she spends time with her incredibly supportive husband and very opinionated 4 year old on their farmette with their horse, miniature donkey, lambs, ducks, chickens, 2 dogs, and 2 cats.
