Why this idea?

We firmly believe that the trend towards the chain or the lone warrior practice are discontinued models.

Our idea is to offer the good family veterinarian on a clinic-like level in cooperation with colleagues of different specializations for the patient owner.

Dr. House is certainly a popular example - as a team, we often come up with better solutions for the benefit of the patients.

In addition, a detailed conversation with the patient owner is important - he is ultimately the one who has to decide together with the veterinarian which way he wants to go in the treatment of his favourite. 

In addition, we want to relieve our veterinarians so that they can take care of what they enjoy most - curing patients. Administration, marketing etc. should not be a burden.

Extensive availability for patients with a simultaneous work-life balance is essential.
