Nurse Practitioners

Tri State Bariatrics Nurse Practitioners


A Nurse Practitioner (NP) is a Registered Nurse (RN) who has graduated from an approved Master’s Degree program that provides additional education and experience in a specialized area of practice. This enables them to become licensed and sit for a nationally recognized certification exam. NPs must renew their license every three years and update their national certification every five years through ongoing education and training.

Nurse Practitioners diagnose, treat, and prescribe medication for a patient’s condition that falls within their specialized area of practice. They provide high quality, evidenced based health care services, and are mainstream providers found in both primary and specialty care. Their focus is on health promotion, education, counseling and disease prevention. NPs work closely with patients listening to concerns, explaining health options and providing appropriate diagnosis and treatment. They provide individualized care resulting in high levels of satisfaction.


Services provided by NPs include physical examinations, diagnosis and treatment of illness, prescribing medications, ordering and interpreting laboratory/diagnostic tests, educating patients about healthy lifestyles and coordinating health care services.

The Nurse Practitioners at Tri-State Bariatrics are all well-trained in managing the weight loss programs of our Bariatric Surgery patients.
