Nichole Mahnert, MD

Minimally Invasive Gynecologic Surgery, Gynecology, Obstetrics and Gynecology

Physician, Banner Health Center plus at Arcadia
I became a doctor because I wanted to take care of women throughout their lives, which is an exceptional privilege. I have advanced fellowship training in the medical and surgical treatment of endometriosis, abnormal vaginal bleeding, and fibroids. When needed, I advocate for minimally invasive surgery (vaginal, laparoscopic, and hysteroscopic). I prefer a holistic approach in my practice and like to work with my patients together to make the best treatment plan for their individual needs.

Sonia Brunson, FNP

Women's Health

Nurse Practitioner (NP), Banner - University Medical Center Phoenix - Banner - University Medicine Family Medicine
As an Addiction Medicine provider, my approach to care delivery is to improve the quality of life and enhance wellness for my patients. I believe in the collaborative approach in treating patients with substance use disorders and that they are treated with dignity and compassion. Treating addiction involves a multifaceted approach involving science, research, wellness, and collaboration. Recovery is a journey, and the patient is the driver in their personal journey. At our clinic, we have a comprehensive team of addiction medicine providers, psychotherapists, social workers, peer advocacy and wellness coaches to help treat, educate, and support our patients through their recovery and provide the best outcomes for them, their families and loved ones.
