My mission is to provide unbiased care to all individuals I encounter in my practice.

It gives me great pleasure to care for individuals in what may be some of the happiest and most vulnerable moments of their lives. I am passionate about getting to know patients and their families as we create partnerships to help them navigate their pregnancy and birth journey. It is my goal to help empower patients to make informed decisions about their pregnancy, health, and birth by providing them with knowledge and guidance.

Outside of work, I love spending time with my husband and children. My hobbies include refinishing furniture and woodworking.

In my career as an emergency physician, I have gotten to take care of patients in both the usual emergency department setting as well as some other unusual environment. Regardless of the location, one thing remains the same - it is about the patient and the care they need at a time of medical crisis. I spend most of my time outside of work, still engaged in medicine with a variety of emergency response organizations as well as the military.

My mission is to guide and empower patients as active participants in their care to promote a healthy lifestyle and prevent disease throughout their lifespan.

As a Primary Care NP, having the ability to form lasting relationships with my patients is what I find especially unique and rewarding. I highly value a holistic approach to patient care, as I believe comprehensive health expands beyond the physical aspects. I want to work together with each patient, since more successful outcomes are achieved through a mutually agreed upon and individualized plan. I like to practice what I preach by living a healthy, active lifestyle outside of work that includes running, yoga, hiking, spending time with family and friends, and traveling.

My treatment philosophy is to help educate individuals on their role in disease prevention and develop relationships with patients—working as a team to manage both chronic and acute health issues. I believe that each individual has their own unique set of circumstances that influence their health and working together to overcome barriers is an essential part of providing healthcare. I consider it a privilege getting to know patients and families and always look at the big picture when caring for individuals. Outside of work I love spending time with my family, going to the beach, gardening and hiking. I am teaching myself how to ice skate so I can play hockey with my boys! 

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. 

I strive to provide high quality, safe, comprehensive anesthesia services and care to all my patients in the perioperative period. 

In the 8 years that I have been practicing anesthesia, I am resolute in my belief that creating and fostering a team environment with effective communication is crucial to developing an atmosphere of trust and the key to providing high quality care inside and outside of the OR with patients and colleagues alike.  As a collegiate athlete and previous marketing manager in my first career, I try to bring these skills and values into the OR and Anesthesia department. Outside of work, I love recreating in the outdoors. From snowboarding, hiking, biking, to waterskiing, beach lounging and lake time with my family, I love it all. Most importantly I love spending time with my husband and two daughters.

Every patient has unique challenges and circumstance of their disease.  My goal is to provide expert care that is tailored to the patient and their family's needs.  Using advanced and proven minimally invasive techniques such as thoracoscopy, robotic and endolumenal treatments, my goal is to minimize pain and accelerate the recovery process so that patients can return to their normal lives.  For patients with cancer, a thorough workup and expedited care is important in getting treated correctly.  Lung cancer, esophageal cancer, thymomas and mediastinal cancers can be difficult to navigate.  I will shepard patients and families through the tests, consultations, and treatments needed so that patients always know that they are being cared for.  For patients with esophageal conditions such as reflux, hiatal hernias, diverticular disease, achalasia, etc., there are minimally invasive surgical options that can provide excellent symptom relief and improve the quality of their lives.  In addition, I treat the multitude of thoracic diseases including thoracic outlet issues, hyperhydrosis, chest wall disorders such as pectus, metastatic cancer issues, end stage cancer surgical therapy among others.
