We believe our biggest added value is our experience. One of our objectives when we started the JMC Family Office was to assemble a team of people with different and complementary backgrounds, both personally and professionally.

Members of the JMC team all have various expertise in a wide array of activities and topics ranging from operations, engineering and manufacturing to human resources, finance, banking and investment management. This helps us maintain a diverse, collaborative and fun work environment where we can thrive and foster innovation, passion and ambition.
