Rabbi Shapiro was impressed by Rabbi Kreiswirth's proficiency in all aspects of Torah. Rabbi Chaim Ozer Grodzinski was very fond of him and gave his sefer on Tractate Zevachim a warm recommendation (the manuscript was lost during the World War II).
Rabbi Kreiswirth received Semicha from Rabbi Chanoch Henich Eigess.
