Elan Colen, MD - Co-founder and Chief Executive Officer

Elan Colen, MD is a successful business and healthcare C-level executive and visionary, with an eye for early identification of shifting trends and business models that have resulted in successful ventures across multiple industries. Dr. Colen realized early on that business was in his blood. His grandfather had been a successful businessman in Puerto Rico, and upon his family returning to PR when Dr. Colen was 20 years old, he promptly founded a hardware store and cabinet shop together with his brother Chaim and used profits to fund their way through college. After Dr. Colen completed medical school and training at the University of Puerto Rico School of Medicine and passed his board examinations, he promptly once again sought out opportunities which resulted in several profitable ventures.

In 2013, Dr. Colen co-founded SAS Group, a laboratory management company based in Jupiter, Florida, where he served as COO until 2017. From the very beginning, Dr. Colen was able to attract and capture key talent which was responsible for building the strong scientific foundation of the company. Being himself a chemist and physician, he recognized the absolute necessity and importance of having the best scientific team possible, and made always the science, accuracy and precision of the provided laboratory services his priority in the company. In the first two years of founding, he nearly singlehandedly led the company in adding new laboratory management clients, doubling each year the clients under management until departing from an active role with the company to pursue several other challenging opportunities. In addition to co founding SAS Group, Dr. Colen has partnered and aligned himself with several well-known and respected individuals, in diverse business ventures in the interactive entertainment industry, social media and online branding space.

Dr. Colen founded The Colen Group in 2015 with a focus in healthcare and laboratory testing, although that has broadened to include investments and partnerships in other diverse industries. Nonetheless, even subsequent to parting an active role with SAS Group, Dr. Colen has still personally retained the same core scientific team throughout successive laboratory projects which was key in the initial success of his company. This has enabled him and his team to continue valuable partnerships and joint-ventures, providing a wealth of exceptional laboratory experience and knowledge to their partners and clients.

When Dr. Colen isn’t conceptualizing new projects or working hard on existing ones, he enjoys spending his time traveling Europe or attending fashion shows and social events abroad.
