Family Medicine

Board-Certified: Family Medicine 

Dr. Melissa Mercado joined Nirvana Healthcare Management Services (NHMS) in 2022 as a family medicine physician at the Roseville Medical Society (RMS) location. After earning her master’s degree in biomedical sciences (MS) at Rutgers University (Newark), Dr. Mercado received her Doctor of Osteopathic Medicine degree (DO) from Rowan University School of Osteopathic Medicine (Stratford, NJ) in 2018. She completed her residency in family medicine at CarePoint Health Christ Hospital (Jersey City) in the summer of 2021. She is a native Spanish speaker.

Dr. Mercado is Board-Certified in Family Medicine by the American Board of Osteopathic Family Physicians (ABOFP) and the National Board of Osteopathic Medical Examiners (NBOME). Professional affiliations include memberships in the American Academy of Family Physicians (AAFP); the American College of Osteopathic Family Physicians (ACOFP); and the American Osteopathic Association (AOA).

Dr. Mercado is certified to treat both pediatric and adult patients. She also conducts and evaluates preventative health examinations for women. She is passionate about patient education relating to various acute and chronic conditions. Whenever it is deemed appropriate, she implements osteopathic manipulative treatment (OMT). Through continual and candid communications with her patients, she has established meaningful, long-term relationships with them.

When asked to “describe your Nirvana experience,” the first word that comes to mind is “family.” Dr. Mercado feels that all staff members benefit from the collaborative spirit that is evident among individuals and departments. Regarding a particularly meaningful experience at Nirvana, Dr. Mercado recalls a patient who recently came to her with diabetes, which had remained uncontrolled for several years. After educating her patient about its causes, long-term effects, and the measures that can effectively control this chronic disease, her patient is now successfully managing her condition. “This outcome exemplifies the effectiveness of patient education and ongoing communications between the physician and her patient.”
