Our Story
Viva Rheumatology was born from a legacy of exceptional autoimmune care. Founded by Dr. Suyien Zhaz-Leitner, our practice represents the natural evolution of Dr. Catherine Kowal’s respected rheumatology practice, which served the Naples community for over 30 years. When Dr. Kowal decided to transition her practice, she entrusted her patients and medical philosophy to Dr. Zhaz-Leitner, knowing that the same compassionate, expert care would continue. Today, Viva Rheumatology combines this established foundation of trust with fresh perspectives and modern approaches, ensuring that patients receive both the wisdom of experience and the innovation of contemporary rheumatology care.
