Lumina Vision Partners is an acquisitive growth platform focused on the optical retail and optometry industry. Lumina partners with independent practitioners to help them maximize the value of their business asset, while easing their administrative burden, improving work/life balance and often supporting transition planning. 

Lumina creates value for both Doctors and eye care consumers by helping to centralize and professionalize the administrative, non-medical functions of the business. This allows Doctors to focus on delivering the best patient care possible, improves the retail options and customer experience for patients, and creates value for all stakeholders.

Verdantas was started with a vision to build a consulting company focused on improving the world by addressing the toughest challenges facing our natural and built environments today. Over the past 18 months, RTC has brought together an outstanding group of consulting companies that share this common focus. The combined organization now offers a comprehensive suite of environmental, energy, water, civil infrastructure, and green and sustainable engineering services.

RTC launched this new venture with the acquisition of Hull & Associates, LLC (“Hull”) in July of 2020, and has since expanded the organization with the acquisitions of Duffield Associates, LLC (“Duffield”), HSW Consulting, LLC (“HSW”), GeoInsight, Inc. (“GeoInsight”) and Alden Research Laboratory, Inc.(“Alden”).

The platform will continue to grow organically, by providing superior service to its clients, and inorganically, by adding like-cultured firms that expand its geographical reach, complement its services offerings and strengthen its diverse and deeply experienced team of professionals.
