What to Expect

Your First Visit at RENEW

We want you to feel calm and confident walking through our door. Here's exactly what happens when you arrive.

We Actually Listen

Your first visit is a thorough intake — your full health history, your symptoms, your goals. No rushing. No dismissing. We want the complete picture.

Targeted Lab Work

We order the right labs — looking at optimal ranges, not just whether a number is "normal." Most patients leave their first visit with a lab order and a follow-up scheduled.

Your Plan Begins

Sasha builds a protocol designed entirely around you — specific supplements, infusions, or treatments matched to your body and goals, not a template.
