"Start to finish, this was a great experience. Admin, nurses, ultrasound techs, and Dr. Gilvydis did an amazing job and were all friendly and personable... I have not had any of the nagging leg cramps... and no longer get the throbbing achy pain in my calf after a hard Peloton ride."

— Gilvydis Vein Clinic Patient Review

"Instead of addressing my concerns or working with me to create a pain management plan, the doctor dismissed my experiences, assumed my physical concerns were 'all in my head,' and suggested I should take antidepressants—for life."

— United Vein & Vascular Centers Patient Review

"I am thrilled that he has now opened a practice in Wheaton Illinois. It’s fresh and clean and modern. His staff is personable and knowledgeable."
