We had a wonderful experience at CMH. We consulted Dr. Mahadevan for a gastrointestinal issue and Dr. Pushpa for an ophthalmology issue. Both doctors were exceptionally kind, patient, and thorough in explaining our conditions and treatment options. They took the time to answer our questions, which greatly eased our worries and gave us confidence in the care we received. A special thanks to Dr Maha assistant's Catherine and Dr Pushpa's assistant Ida, whose gentl, and compassionate approach made us feel comfortable and well looked after throughout our visits. We're truly grateful for the excellent care and professionalism shown by the entire team. Highly recommended!
