Interdynamics Inc. is a mental and behavioral health firm in Landover, MD. It was founded by Mrs. Joan Branch in 2000 as a management consulting service, but grew later into a mental and behavioral health firm. Our core belief is being ‘interdynamic’ in our approach to mental and behavioral health. To be ‘interdynamic’, we look at all of the factors – all of the dynamics – that play a part in what people experience. We do this so that when our clients leave us, they will know that their needs are taken seriously and are deeply understood.
