Gryphon Investors, a San Francisco-based middle market private equity firm, announced that it has made a majority investment in Water's Edge Dermatology, a leading provider of comprehensive dermatology services in over 30 locations in Florida. The Water's Edge management team has retained a significant ownership position in the company. Terms of the transaction were not disclosed. "At Gryphon, we see growing demand for dermatological services, powered by a rapidly aging population, increasing rates of skin cancer, and rising interest in cosmetic services," said Gryphon Principal Luke Schroeder. "Thanks to its commitment to providing high quality clinical care in convenient locations with a focus on outstanding customer service, Water's Edge is uniquely positioned to use the favorable dynamics in the overall dermatology sector to lead on an even broader scale."
