Auto immune rheumatology recommendation

My partner is in India in Trivandrum, which is a new place for her and her family. We are looking for recommendations for a very good rheumatologist, who also specializes in autoimmune conditions. Our online search so far has brought up these names. Only one of them in KIMS shows as working on auto immune. 1. Dr. Rajesh S - KIMS 2. Dr. Vishad Viswanath - IRIS 3. Dr. Vikraman - SP Fort Does anyone have first-hand experiences with these doctors or others you would highly recommend?
