"Dr. Lahmann made me feel welcome and informed from the very first visit to the BMI Surgery office. He and his partner and their staff are knowledgable, dedicated and caring. They go above and beyond to keep patients informed.rn The pre-surgical education program is vital and well-done. After care is comprehensive as well. I had very rare complications a little over 9 months out in addition to some complications within days of my RNY and on both occasions, Dr. Lahmann and Dr. Joyce saved my life and showed concern for me and my family. Their surgical competence is only exceeded by their interpersonal skills in dealing with patients and their families."
