Following recommendation of the doctor leading my pregnancy I was looking for USG specialist who would be FMF accredited practitioner. So, I had USG of each trimester done by dr. Korzeniewski in the clinic Invicta, Warsaw. The doctor is very calm, detailed, answers all the questions and dissolves doubts, he is never in a hurry, but on the contrary spends good time on doing careful measurements and testing. He is also very polite and patient. Every time after leaving his cabinet I felt well-taken-care-of. Dr. Michał Korzeniewski is definitely the one I would suggest other women.
