Menopause and beyond
Care that evolves with you
As research and treatment options evolve, menopause care continues to become more personalized. Your symptoms, medical history, preferences, and everyday life all belong in the conversation.
Dr. Diana Tran-Kim is here to answer your questions about menopause and your broader gynecologic health—from vaginal dryness and discomfort with sex to bladder concerns and overall wellness.
Her approach goes beyond a prescription. Together, you can explore nutrition, physical activity, sleep, and practical lifestyle changes that support your health through this transition and beyond.
Understand your options
Your visit may include a discussion of hormone therapy, often called hormone replacement therapy, as well as nonhormonal treatments and approaches that do not involve medication. Dr. Tran-Kim will help you weigh the potential benefits and risks in the context of your individual needs.
The goal is a thoughtful plan that fits your health, your priorities, and your life—with room to reassess as your needs change.
