He graduated from school in Münchenstein near Basel in 1987. This was followed by a 6-year study of medical science. He graduated from his studies with a medical degree from the university Basel at the beginning of November 1993.

He started his doctorate thesis during his studies and was granted his PhD from the university Basel in January 1994.

His professional career began in March 1994 and it carried him from assistant doctor of Delémont over Brig (in Valais) to the canton hospital in Winterthur where he reached the maturity for medical specialist in surgery in 2000.

His two daughters Sarah and Annika were born during his formation period (1994 and 1996) and later his two daughters Sofia (2018) and Maxima (2019). Dr. Köstler is married to the lawyer Selime Berk, Maxima and Sofia are the two joint children.

Dr. Köstler gained the focus titles for general surgery and traumatology as well as for visceral surgery at the hospital Limmattal. During the last few years he has been specializing in bariatric surgery (obesity surgery).

In this area he counts as one of the most experienced surgeons in the whole of Switzerland with a total of over 3000 bariatric operations. Right now he is chief doctor for surgery at the hospital Limmattal and is the head of the interdisciplinary obesity team.

Between 2012 and 2017, he held the position of consulting physician for bariatric surgery at the University Hospital Basel. Here he leads the bariatric surgical team.
