Lifecycle Women’s Health

Susan is a certified nurse-midwife (CNM), sexuality counselor (CSC), and menopause specialist. She holds a master of Science in Nursing (MSN) and a Master of Public Health (MPH). She has more than 40 years of experience caring for women across their lifespan. She worked with women and midwives in Israel, Europe, New York City, the greater Boston area, and in Maine.

After practicing as a full-scope midwife, working primarily with pregnant people, Susan now focuses her career on menopause and sexual health at Lifecycle Women’s Health in Brunswick, Maine. She started this practice after personally and professionally experiencing the healthcare injustices people face as they age. She views midwifery as a form of activism and is committed to helping people access holistic midlife and menopausal care.

She is the mother of two grown sons and her lovable 3-year-old rescue pup, Cookie. When she is not advocating for midlife women’s health or seeing patients, she spends her time in nature and loves to share all that Maine has to offer with her friends and family.

Emily Demetriou, is a board-certified endocrinologist at MaineHealth Endocrinology and Diabetes in Scarborough, Maine.  She has practiced clinical endocrinology for the past 16 years, with a special interest in osteoporosis and metabolic bone disease. She teaches Tufts medical students about calcium metabolism and bone physiology and supervises Internal Medicine residents rotating in endocrinology. Dr. Demetriou attended Dartmouth Geisel Medical School. She trained in internal medicine at Maine Medical Center (including a chief year) and in endocrinology at Boston Medical Center. She is also a certified clinical densitometrist. She lives in Falmouth, Maine, with her family and loves outdoor activities like biking, skiing, and rowing.

Dr. Jessica Oehlke is a double board-certified physician in Sleep Medicine and Psychiatry who specializes in women’s sleep and circadian health. She is the founder of Lakeside Sleep Care, a telehealth sleep clinic, and Sleep for Women, an education and advocacy platform dedicated to improving women’s health through sleep.

Dr. Oehlke completed her undergraduate studies at Cornell University, graduating magna cum laude in Biology and Society, and earned her medical degree from Albany Medical College. She completed her psychiatry residency at the University of Vermont Medical Center, where she served as Chief Resident, and went on to complete a fellowship in sleep medicine at the University of Pennsylvania.

Dr. Oehlke has authored a book chapter on insomnia, published in the sleep literature, and taught at both the University of Vermont Medical Center and Dartmouth-Hitchcock Medical Center. She has also presented at sleep conferences on topics related to sleep and mental health.
In her free time, Dr. Oehlke enjoys spending time with her husband, their two daughters, and their dogs, as well as being outdoors. She is an avid runner and has completed five Boston Marathons.

Steph studied psychology at the University of Vermont before devoting her career to movement and healing, finding yoga to be one of the most effective modalities for supporting mental health and well-being. For more than a decade, she has guided yoga in studios across the country — from the Florida Keys to California’s redwoods — as well as in virtual spaces worldwide. She is known for upbeat, strength-based classes and grounded, intuitive cueing that helps students feel capable and at home in their bodies.

Originally from the Finger Lakes region of New York, Halle earned her Doctor of Physical Therapy degree from the University at Buffalo. Her career began with travel physical therapy, which brought her to Vermont, where she quickly fell in love with the state’s beauty and community.

For four years, Halle worked at Copley Hospital, where she discovered her passion for outpatient orthopedics and pelvic floor physical therapy. She then joined the Summit Team in 2025. She is especially drawn to pelvic floor rehab because it remains an underutilized resource with the power to make a profound difference in people’s lives.

Halle loves being a physical therapist because it allows her to connect with people, understand their goals, and help them return to the activities they enjoy most. Outside of work, she enjoys spending time with friends and family, cooking, gardening, golfing, hiking, and skiing. She is a huge Buffalo Bills fan and loves watching any and all sports.
