About Premier Medicine and Wellness
Dr. Kostacos is an internist who runs a small concierge primary care practice in Horsham, affiliated with the Ms.Medicine network. She sees adult women and men, and menopause and hormone therapy are part of her everyday care rather than a separate clinic. Members get unhurried visits with her and can reach her directly by phone or email at any hour. People who don't want a membership can book a single extended consult about one concern, such as a second opinion on menopause symptoms. She is also board certified in obesity medicine and writes that there is no five year cutoff for hormone therapy, only a yearly check on whether it still makes sense. New patients start with a meet and greet visit, and some visits can be done by video.
