About Nexus HealthSpan

At Nexus HealthSpan in Lake Forest, California, Zachary Lott, MSN, ARNP, AGACNP-BC, and his team offer a unique approach to better health using personalized and patient-focused care that emphasizes whole-body wellness. They treat the person, not just the condition. 

The team spends the time to get to know each client, forming strong connections that lay the groundwork for success. Their holistic approach combines traditional medicine with cutting-edge treatment modalities to better serve each person’s unique needs. 

The Nexus HealthSpan team focuses on vascular health and cardiovascular disease prevention. Through customized care, they help patients prevent strokes, heart disease, heart attacks, and other serious health threats, while improving their sexual 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 Zachary to create customized holistic treatment plans for men with these problems. 

Some popular treatments available at Nexus HealthSpan include platelet-rich plasma (PRP) treatments and focused shockwave therapy. 

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

This led Zachary to develop evidence-based personalized treatment plans for adult women with menopause symptoms like low libido, hot flashes, and mood swings. Many women also come to Nexus HealthSpan for help with premenstrual dysphoric disorder (PMDD), polycystic ovary syndrome (PCOS), premenstrual syndrome (PMS), and other women’s health disorders. 

Clients report significant improvements in bodywide health, including better mood, more energy, improved brain function, stronger immunity, and improved sexual health.

To better manage all of the underlying factors that can lead to poor health and improve all aspects of wellness, call Nexus HealthSpan, or click on the provided link to arrange a consultation.
