MD Marketing Agency

Alex Sidorenkov is CEO and marketing strategist at MD Marketing Agency, the South Florida firm that operates under the Wellness Clinic Marketing brand. The agency positions itself narrowly: patient acquisition for cash-pay medical wellness practices, with a focus on hormone optimization, medical weight loss, sexual health, men's health, and med spas. Sidorenkov leads a team of roughly twenty specialists spanning media buying, paid search, web development, medical content writing, and marketing automation, with a dedicated AI specialist and a sales director supporting client onboarding.

The public founder story on the site is brief; the About and Team pages emphasize the firm's collective track record rather than a detailed personal biography. What the site does state is that the agency has spent the past decade working with medical wellness practices and concluded that digital advertising is the most effective channel for cash-pay clinics to generate new patients. That conviction shaped the firm's proprietary PatientFlow Acceleration Program and its MAR$ Practice Accelerator framework, which bundles paid media, CRM automation, and AI-driven follow-ups into a single system.

The thesis guiding the agency is specific: cash-pay wellness verticals — HRT, GLP-1 weight loss, sexual wellness, aesthetics — behave differently from insurance-based medicine and require marketing built around consumer-style buying behavior, high-ticket consultations, and aggressive lead nurture. Rather than extend into general healthcare marketing, the firm has stayed inside the wellness and med spa lane and expanded horizontally into multi-location and franchise support for operators scaling across markets.
