The Jean Walter Infusion Centers are committed to providing a safe and professional environment where our patients enjoy a relaxing experience while receiving their infusion/injectable treatment in a state-of-the-art facility.

Our founder, Dr. Nasser Nasseri, is a board-certified rheumatologist, who is also chief rheumatologist at both St. Agnes Hospital and MedStar Union Memorial Hospital, as well as founder and president of NCARD. Dr. Nasseri has over 16 years of experience in training medical residents how to diagnose and treat autoimmune inflammatory diseases with IV infusion and injectable medications and has assembled a very professional, dedicated, and experienced team at the Jean Walter (JW) Infusion Center.
The JW medical team is directed by Dr. Jeffrey Landis, who has been practicing rheumatology for 8 years and has 10 years of experience with IV infusions and injectable medications for the treatment of autoimmune diseases.
