Our Consultants and Associates

We are an interdisciplinary team of experts, partly shareholders (Executive Partners) and partly competence partners (Associate Partners) plus carefully selected associates that have to remain independent due to legal implications connected to their profession. Together, as

The Acornpark Leaderspoint Associates

we provide our first-class individual Acornpark® and Leaderspoint® services. Our unique line-up gives us the necessary flexibility to serve our clients in a custom-fit manner. Our special positioning, with which we support both companies and individuals, demands broad, deep and sometimes only selectively required competence on our part. We have successfully balanced out these requirements for many years, enjoying excellent reputation with our clients.
