Because Dr. Kass is one of the few physicians in the country who specializes and is board certified in the field of Phlebology (the diagnosis and treatment of venous disorders), you will receive expert care for your vein issues. Dr. Kass understands the vast spectrum of vein problems, from relatively mild to very severe, and employs the latest technology available to treat venous conditions using highly effective, non-surgical methodology. TRUST THE EXPERT.

For 15 years, Dr. Kass practiced as a board certified anesthesiologist in the field of trauma and critical care. He was educated and trained at the finest institutions in the country. Drawn to Phlebology, he advanced his expertise with some of the world’s leading experts in the field of treating venous disease. Since then he has dedicated his career to the study, prevention and treatment of venous disorders.  In 2000, he founded a specialized, private medical clinic to treat men and women for venous disorders to achieve a better quality of life without the downtime and cost of surgery.

Today, Dr. Kass continues to offer the highest level of non-surgical care for vein therapy, cosmetic care, hemorrhoid treatment, and healthy aging. Dr. Kass is here for you, helping to enhance your life through his unique blend of medical knowledge, compassion and ethical treatment plans.
