Our investment philosophy is based on the early identification of growth, wherever growth exists.

Since our founding in 1976, we have remained firmly committed to a consistent investment philosophy.

Essex Investment Management is an independent, employee-owned institutional investment firm that incorporates environmental sustainability and social factors into our portfolio management process. We believe the environmental, social and governance (ESG) factors of a company can determine investment differentiation and opportunities as well as uncover risks. We believe that innovative solutions will solve the world’s critical challenges.
