Dan Monahan, MD

Dan Monahan is board-certified in surgery and a fellow of the American College of Surgeons.  His formal training included more experience in vein treatment than typical surgical training, and he carried this expertise into his practice at Monahan Vein Clinic in Sacramento, California. He is the only physician in the Sacramento region to focus his entire practice on the treatment of vein disease.

Dr. Monahan is a member of the American Venous Forum and the American College of Phlebology. He graduated from the University of California at Davis in 1976. Returning to his home in Hawaii, he attended medical school at the University of Hawaii. Post-graduate training took him to the Cleveland Clinic, and then to Virginia Mason Clinic in Seattle, Washington, where he completed his general surgery residency in 1987.

Dr. Monahan has done clinical research looking into the best way to treat varicose veins. He published the results of a study in the Journal of Vascular Surgery that challenged a century-old dogma of vein treatment. Many vein experts have now accepted this concept and the implications it has for changing vein treatment strategies. Physicians from the United States and abroad have visited his practice to learn vein treatment techniques.
