Prior to joining Cohasset Pediatrics I practiced pediatrics south of Boston for nine years and was Chief of Pediatrics for four years within that practice.  

I received my undergraduate degree in Drama from New York University’s Tisch School of Arts.  Working as an actress afforded me the opportunity to travel professionally and experience life as a performing artist in New York City, Los Angeles and London. While working in show business was certainly exciting, I found my true calling working as a physician partnering with parents to help provide the best medical care for their children.

When not at work, I love spending time with my husband and two children and enjoy singing when I get the chance.

I chose family medicine so that I could treat a wide spectrum of medical conditions and so that I could treat all ages, including newborns and multiple generations, in one family. This helps me to treat the whole person because knowing a person's social background is essential. I firmly believe that emotional and mental well-being are key factors in maintaining good overall health.

I grew up in Quincy and love living and working near my family and friends. I enjoy spending time at the beach, traveling to exotic places, going out dancing, skiing, cooking/baking, and following Boston sports teams.

My mission is to treat my patients with compassion and kindness and take the time to know and understand them.

I am certified by the American Board of Internal Medicine in Internal Medicine, Medical Oncology and Hematology. I received my BA in Biology at State University of New York at Buffalo and my MD from Jefferson Medical College of Thomas Jefferson University in Philadelphia, PA. I did my residency in Medicine at Lankenau Hospital in Philadelphia, PA and Fellowship in Hematology-Oncology at University of Connecticut Health Center in Farmington, CT. I was recognized in Boston Magazine's 2017 Top Doctors list. Outside of work, I enjoy listening to classical music, traveling, running, and bicycling. 

My career started in the US Army and it was a privilege to serve and care for women in the military and their family members while training at Walter Reed Army Medical Center and then stationed overseas in Germany for 4 years. I returned to the South Shore area since this is home and have been been fortunate to raise my family and to practice here since 2002. I am so grateful to have the opportunity to care for the women in our community. Although I transitioned to a more administrative role, I continue to practice obstetrics and gynecology here in the hospital and will continue to strive to offer the best care to patients through open communication and strong relationships.

When not at work, Liana can be found spending her time with family, friends, and her rescue dog. She loves to travel to new cities and countries and learn about different cultures. She also loves to give back to her community.

It has been my privilege to practice medicine and to have made a difference in the lives of my patients over the past 21 years. I enjoy the challenges of practicing internal medicine in a hospital setting and working as part of a team with our excellent hospitalist providers, consultants, nursing and ancillary staff. I served as Medical Director of the Hospitalist Department from 2009-2015 and am proud to say that we have an amazing program with dedicated clinicians who genuinely enjoy the care of hospitalized patients and are committed to excellence in their every day work. I enjoy giving back by participating in the Pan Mass Challenge which raises critical funds for cancer research and the Multiple Sclerosis cycling events. I enjoy boating, hiking and camping, and long distance bicycling and, most importantly, spending time with my family.
