Melwyn Sequeira, M.D., is a general and endocrine surgeon with MidMichigan Health and currently welcoming new patients. He also serves as the oncology service line chief and is responsible for ensuring the highest quality and consistency of cancer care at MidMichigan.

Dr. Sequeira is one of only a few surgeons in the state who specializes in endocrine surgery, which includes thyroidectomies, parathyroidectomies and adrenal surgeries. It was during the completion of his surgical residency at Mayo Clinic in Rochester, Minnesota, that he developed a keen interest in endocrine surgery. Following the completion of his training at Mayo Clinic, he was recommended for an endocrine surgery fellowship at University Hospital, Lille, France, which he completed in December 2006.

Philosophy of Care

Dr. Sequeira believes the exchange of knowledge between the physician and patient builds a strong relationship.

“I realize there is an abundance of resources my patients may look to when they have a concern about a medical condition,” said Dr. Sequeira. “I encourage my patients to do their research so we can have a mutually beneficial discussion. In this way, we build a strong relationship and a better plan of patient care. It is always my goal to have my patient satisfied and see a smile on their face.”

“What I like most about the specialty of endocrine surgery is the ability to tie in the artistry of working with my hands with analytical thinking,” said Dr. Sequeira. “This combination offers me a great challenge and sense of satisfaction.”

Special Interests and Procedures

Dr. Sequeira specializes in a variety of general and endocrine surgeries. These include thyroidectomies – all types, parathyroidectomies – standard open and minimally invasive parathyroid surgery, thyroid cancer/neck dissections, open adrenal surgery, laparoscopic adrenal surgery, endocrine tumors of the pancreas, endocrine tumors of the gastrointestinal tract, breast surgery/sentinel node biopsy and gastrointestinal malignancy.

Dr. Sequeira is married to Dr. Sunita Vadakath, who currently serves as the service line director for cardiovascular service at MidMichigan Health. They live in Midland with their two daughters.
