About Our Practice
A unique professional relationship
Helena OB/GYN Associates
Choosing an OB/GYN provider is a very personal choice.
Our Board-Certified Obstetricians and Gynecologists, Dr. Jack W. McMahon and Dr. Alexis O’Leary believe that every woman deserves a choice for her obstetrical and gynecological care. Dr. McMahon has been a trusted provider in the Helena area since 1990, and we welcomed Dr. O’Leary to our practice in 2018. Dr. McMahon and O’Leary consistently provide exceptional, attentive obstetrics and gynecological care in a supportive, compassionate environment. Our providers, in collaboration with other physicians in the Helena community strive to provide our patients with the best care available.
In addition, our practice is unique because we offer choices in providers, as well as compassionate care. Our Nurse Midwife, Sue Ditchey-Hellems, and Family Nurse Practitioner, Denise Smigaj understand the personal needs, concerns, and preferences of women, from adolescents to menopause and beyond. All of our providers facilitate a supportive environment that fosters genuine listening, open communication, patient comfort, education, and the best obstetrical and gynecological care available. We believe in educating our patients to make informed decisions about their health and present a full spectrum of choices, including but not limited to:
annual well-women exams | infertility treatments | natural childbirth and birthing options | care for High-risk pregnancy | family planning choices – Mirena IUDS – Depoprovera – Nexplanon | menstral problems | pelvic pain | endometriosis | STD screening | menopause management | hysterectomy | bladder repair
