Through personalized care, the Nexus team helps patients prevent heart attacks, strokes, and other serious health threats, while improving each individual's health and other areas of concern.

Common men’s health problems, like low testosterone and erectile dysfunction, usually stem from a greater vascular health issue, which led Mr. Lott to create a customized holistic treatment plans for men with these problems. Some popular treatments available at Nexus include extracorpeal focused shockwave therapy (ESWT), testosterone replacement therapy (TRT), and the Priapus Shot®, or P-Shot®.

Because male clients saw tremendous improvements in their health and sexual wellness through these treatments, The Nexus team started to wonder whether the holistic approach could help their female partners who struggled with sexual and whole-body health. 

This led Mr. Lott to develop evidence-informed personalized treatment plans for adult women with menopause symptoms like low libido, hot flashes, and mood swings.
