Internationally recognized cosmetic dermatologist Dr. Janet Allenby joins Aviva's growing national network of founder-led aesthetic practices
CHICAGO, Oct. 25, 2026 /PRNewswire-PRWeb/ -- Aviva Aesthetics, the only entrepreneur-owned national platform built for medical aesthetics practice owners, today announced that Allenby Cosmetic Dermatology, founded by board-certified dermatologist Dr. Janet Allenby, has joined its growing network of practice partners. The partnership marks Aviva's first practice location in Florida and expands the platform's presence into one of the country's most established aesthetics markets.
For nearly three decades, Dr. Allenby has built one of South Florida's most recognized names in cosmetic dermatology, earning a reputation for combining medical expertise with an artistic, natural approach to aesthetic care. Today, Allenby Cosmetic Dermatology holds a 4.8-star Google rating with more than 440 patient reviews, reflecting the trust and loyalty the practice has built within its community.
"Dr. Allenby represents exactly the type of founder we want within Aviva," said Tyler Weinberg, CEO of Aviva Aesthetics. "Over more than 30 years, she has built Allenby Cosmetic Dermatology into one of South Florida's most established medical aesthetics practices, supported by an exceptional team and a reputation that extends well beyond the region. Entering Florida alongside a founder and practice of this caliber marks an important milestone, and we are thrilled to welcome Janet and her team to Aviva."
Founded in 1995, Allenby Cosmetic Dermatology has become a destination for advanced, non-surgical aesthetic care in South Florida. Dr. Allenby is a recognized leader in cosmetic dermatology and injectable techniques and is known for her signature "Allenby Touch," an individualized approach designed to enhance each patient's natural features. Her expertise has been featured in publications including Allure, InStyle, ELLE and NewBeauty, and she has been invited to share her expertise at conferences, industry events and pharmaceutical engagements nationally and internationally.
Having explored private equity opportunities over the years, Dr. Allenby was looking for a partnership that reflected both the value of what she had built and her ambitions for its future.
"After nearly 30 years of building this practice, I wanted our next chapter to reflect both what we have created and where I believe our industry is headed," said Dr. Janet Allenby, Founder of Allenby Cosmetic Dermatology. "I've been approached by PE over the years, but Aviva offered something much more forward-thinking: the opportunity to grow alongside other accomplished founders, benefit from the scale of a national platform and maintain full ownership of my practice. It's a fundamentally different approach — one that allows us to preserve the culture, identity and patient relationships that define us while positioning us for greater long-term financial upside as we build a stronger business together."
Aviva's proprietary Entrepreneur Equity™ model challenges the traditional private equity playbook by keeping founders at the center of both decision-making and financial upside. As Aviva continues its rapid expansion across the country, it brings successful independent practice owners together to strengthen operations, improve purchasing power, share best practices and build greater long-term enterprise value.
The addition of Allenby Cosmetic Dermatology further strengthens Aviva's growing national footprint while establishing the platform's presence in Florida.
