I feel so lucky to be a patient at Chicago Vein Institute. I have been getting treatment for leg vein issues there for several years and the high quality of their care never varies. The staff is always very professional and friendly. They make sure to explain what each procedure will entail and what I need to do after my appointment. Before coming to them, I had constant leg pain, but thanks to them, I am now pain free and I can do the activities I like to do-play tennis, ride my bike, take Pilates classes-without worry. I can’t recommend CVI highly enough.

I’ve had an excellent experience with the Chicago Vein Institute. From the moment you walk in, the office staff is warm, welcoming, and always ready to help. The medical assistants are incredibly knowledgeable, professional, and have such a great bedside manner — they make you feel at ease while checking vitals, applying stockings, and doing wraps. The doctors are equally wonderful: friendly, patient, and thorough in answering all my questions. They take the time to ensure I feel comfortable and fully prepared for each procedure. Throughout my visits, the entire team has consistently demonstrated professionalism and trustworthiness. I genuinely feel cared for here and highly recommend the clinic to anyone seeking vein treatment.
