I have been a patient of Dr. Rennart for approximately 8 years. In this time the doctor has helped me prolong my working career and life through medication therapy and education. He is kind, empathetic and knowledgeable in his field of expertise. I would gladly recommend him to all family and friends suffering from pulmonary or coronary diseases. He is truly blessed in his field. Thank you Dr. Rennart!! Respectfully, Mike
