Dr. Guillermo Ferrer earned his medical degree from La Universidad del Zulia, Maracaibo, Venezuela in 1980. He completed his internship at the Hospital General Santa Barbara, Venezuela in 1982.

He completed his post graduate training at Brookdale Hospital Medical Center in Brooklyn, New York in the general surgery residency training program 1982-1987. Here, he served as the Chief Resident of Trauma Service 1985-1986 and Chief Resident 1986-1987. He went on to complete a Fellowship in Cardiothoracic Surgery at the Newark Beth Israel Hospital in Newark, New Jersey in 1987. He has done honorary work in the Honduras to assist the poor in need of surgical care at a Catholic Charities Hospital. He has also served as the Chairman of the Department of Surgery at Cayuga Medical Center.

Dr. Ferrer began his career with a general and vascular surgery practice. He started the Northeast Surgical Group with Dr. Juan Agostini. He became interested in the treatment of veins and was the only physician in the area with a Venous and Lymphatic Medicine specialty degree. Dr. Ferrer became a pioneer in the Ithaca area treating all stages of varicose veins and spider veins, as well as venous diseases such as venous leg ulcers, phlebitis, and chronic leg swelling.

Dr. Monoghan joined the practice in 2003 and, with Dr. Ferrer, started the Ferrer and Monaghan Vein and Aesthetic Center. Dr. Ferrer currently dedicates his practice to venous and lymphatic medicine, as well as dialysis access.

“There is a misconception that varicose veins are just a cosmetic nuisance,” says Dr. Ferrer. “Left untreated, the condition can lead to clots, vein thrombosis, and limb-threatening ulcers. If we can treat patients early on, we can prevent the complications of venous disease. Technology has changed significantly. Now, we have laser, radiofrequency, and cyanoacrylate glue. Most procedures can be done in the office with little or no pain and very little down time. And, most treatments are covered by insurance.”
