“As Physicians, our daily commitment to doing what’s best for our patients is inspiring, honorable and challenging. Our profession allows us to enter people’s lives in moments of vulnerability, and trust is the main foundation for this relationship. Part of how we earn and maintain this trust is through the highest standards we as physicians collectively embrace throughout our training in medical school, residency and fellowships over a decade of hard work and sacrifice.  This is only achieved by complete dedication and love for our patients and medicine.

I salute every physician who puts their patient’s well being first and follow his/her Hippocratic oath to the fullest.

Medicine is not only a science but it is also an art. We are all created uniquely with different DNA. Therefore, the same treatment plan may not present the same results all the time.

Education, Evaluation and Unique Treatment Plan are the hallmarks of Heart and Health Medical. Our expert medical team will develop the best treatment plan for each patient. The first goal of our medical team is to evaluate each patient with the latest technology and diagnose the underlying disease. We take our findings and then educate our patients on their medical condition. We rather treat the underlying disease than the symptoms alone.   It is only then that  THE PATIENT should make the final informed decision regarding his/her health with complete medical support from us. "
