The Ars Artis Medical Publishing Ltd. was established by the author in 2022.
The „ars artis”; is a latin term, means: professional expedient.
This is our creed to produce professional books, with different aspect to the conventional.
The BPS Step by Step is a handbook which evokes a BPS hands-on course, and it’s aim to involve the reader, to feel the atmosphere of a real live-patientcase BPS treatment as in clinical, and technical aspect. I hope than the topic and the explanations will be well understandable, and useful for the daily work.
