”Outstanding preventative cardiologist. I drive from South Orange County because of her exceptional expertise and ability to communicate. Her staff is excellent. So happy to be her patient. Too many cardiologists are in a reactive posture rather than actively working to prevent cardiac events from happening. Dr Paul is very proactive. Highly recommend.

”Outstanding Cardiologist with True Compassion and Expertise. I had the privilege of being treated by Dr. Sumita Paul, a Harvard-trained cardiologist whose expertise and dedication truly stand out. From the very first consultation, it was clear that she combines exceptional medical knowledge with genuine care for her patients. Dr. Paul takes the time to listen carefully, explain every detail, and ensure that you understand your condition and treatment options fully. Her calm and reassuring approach immediately builds trust and confidence. What sets her apart is not only her world-class education and skill, but her deep passion for helping her patients live healthier, fuller lives. She goes above and beyond to provide personalized care, always following up and ensuring that no question goes unanswered. In a world where many medical visits can feel rushed, Dr. Paul makes you feel truly seen, heard, and cared for. I feel incredibly fortunate to have her as my cardiologist — she embodies the perfect balance of knowledge, compassion, and dedication. I would highly recommend her to anyone seeking top-quality heart care from someone who truly loves what she does.

”Dr. Sumita Paul is an exceptional cardiologist who has cared for my mom with both skill and compassion. She takes time to listen, explains everything clearly, and makes sure we always feel comfortable with her care. Her thoroughness and genuine concern for his patients have truly given our family peace of mind. I also want to recognize Rosa at the front desk. We’ve known her for the last 40 years, and she has always been absolutely wonderful. She is kind, helpful in every way, and makes each visit a positive experience from the moment we walk in. We are so grateful for both Dr. Paul and Rosa they make an outstanding team, and we feel blessed to have them supporting my mom’s care.

”I have been coming to California Cardiac Institute Medical Group for more than 25 years. Several months ago I came to the clinic and saw Dr. Sumita Paul, for the first time. My interaction with Dr. Paul and my experience with the Clinic was excellent. She is very thorough and detailed. Today I brought my wife, a registered nurse, to see Dr. Paul. We both are extremely happy with the care we received under Dr. Paul’s care. Thank you, Dr. Paul for being our Cardiologist! I will recommend all my friends & relatives to come and see Dr. Sumita Paul.

”I started seeing Dr. Paul back in April for some concerns regarding my heart rate and I could not be happier to have found her! Right when I walked in for my appointment I was greeted nicely from the front desk and did not have to wait long to see the doctor. Dr. Paul made sure to ask the right questions and order tests that would allow her to see what the next steps would be. She is understanding and listens and does not take the easy way out like some doctors. I was appreciative of her knowledge and patience with answering all my concerns and questions. Now as I write the this review in July I can only say great things about Dr.Paul and her team! They are truly wonderful and I enjoy going back for my follow up visits each time. Thank you so much Dr. Paul and your fantastic team for such a great environment!
