If I could give this guy 10 stars I would. He was the 4th Dr that evaluated my 20 yr old son with hip pain. The other drs all said he had a muscle tear but he wasn’t getting better. He was in excruciating pain, not able to walk, sit, sleep, he was in bed for days, and home from college because he couldn’t care for himself at the dorm. Within 24 hours of seeing Dr Siva (who did not believe it was a muscle tear), he was pain free and planning to return to school. Love this Dr!!

Came in with a nagging shoulder issue. He talked with me at length about my options and treatment plans. I left there feeling satisfied we are going to fix this issue once and for all. I like how deeply he explained my problem and the steps we can make to address it in a conservative, yet complete way.

I’ve been seeing other doctors for almost 3 years for my hip injuries and never had my problems correctly explained to me until I went to Dr Siva! He described everything to me that made sense and was very understanding of all of my struggles with my pain. He gave me all my options and the pros and cons of each option. Highly recommend

Dr. Siva was very professional yet friendly and genuine. He made me feel very comfortable right away. He addressed my concerns quickly yet efficiently. Very happy to have seen him and would highly recommend him!

Dr. Lakshmanan Sivasundaram is a specialist in pain relief and sports medicine. He is knowledgable, concerned, respectful, friendly, courteous, unhurried, and offers his patients his patients his full attention. He is a good listener. He offers alternative solutions to the problem. He manages his time well, and the wait time is quite short. Dr. Siva is a really nice joint pain specialist and surgeon. I would highly recommend his services for his areas of expertise.

Dr. Siva is an exceptional doctor. I recently had the privilege of being under his care following a car accident that resulted in a severely fractured clavicle. He is compassionate, professional and very knowledgeable. He always puts his patient’s needs and safety first and that is very important. From the moment I met him, I never felt rushed. He took the time to address all of my concerns and ensured I fully understood his recommendations. He was by my side at every stage, monitoring my progress closely and making adjustments to the treatment plan when necessary. It’s clear that he sees beyond just the injury; he cares for the whole person. His genuine concern for my well-being was evident in every interaction we had, making me feel heard and supported throughout. I cannot recommend Dr. Siva highly enough to anyone in need of orthopedic care. Thank you, Dr. Siva, for your exceptional care and unwavering dedication to your patients’ well-being.

Dr. Siva is a great surgeon with a bedside manner beyond compare… follow up was great and I would recommend him to anyone.
