Dr. Shantha was my doctor for several years and yesterday my husband and I reestablished with him. He is knowledgeable and professional in all he does. He takes the time to examine and listens to your questions and concerns. His Office Staff are very polite and helpful, we highly recommend him to anyone needing a Pulmonologist.

I take my mother in law to Dr Shantha. He always takes his time and listens to her needs and answers all questions she has. Love the new office. He is very considerate and never rushes the appointment. We are so happy he is her doctor.

My dad had an appointment for the first time with Dr. Shantha after he was dismissed from the hospital and Parkridge Medical Center Rehab. Dr. Shantha and his staff were friendly and professional, and took the extra time to assist my Dad who was in a wheelchair at the time, even though we knew they were extremely busy. Dr Shantha took the time to explain things thoroughly to my parents, and was extremely helpful in setting up a future sleep study and follow up to determine what sleep aids dad would need. (Frankly, as a daughter and a nurse, I really appreciate them going the extra mile.). A big shout out and thank you to Dr. Shantha and all of his staff—Way to go!
