My journey into medicine began at Quinnipiac University where I graduated Magna Cum Laude receiving a BS in Biology with a Chemistry minor. I then attended medical school at Stony Brook University School of Medicine where I received the Gold Foundation for Humanism in Medicine recognition. After this I moved to NYC where I completed my residency at Jacobi Medical Center at the Albert Einstein College of Medicine. Training in the Bronx was a challenging, but incredibly rewarding experience. Following completion of my residency I had the privilege of being Chief resident. During my chief residency year I spent time working as a general pediatrician in the clinic as well as a hospitalist on the pediatric ward. I also spent time mentoring and teaching both medical students and residents. I have received letters of commendation for excellence in teaching throughout my training. I am currently a board certified pediatrician and I am looking forward to becoming a board certified lactation consultant.

I recently became an International Board Certified Lactation Consultant and a NYS Registered Lactation Consultant. It has helped me broaden my perspective and care for nursing moms.

I was born and raised on Long Island and I love spending time with my family and friends. I enjoy traveling and experiencing new cultures and foods.

Caring for children is truly my passion. I deeply value the relationships I have with my patients and their families. I am thrilled to be a part of the Happy & Healthy Pediatrics team and will strive to provide excellent care for every child and support and peace of mind for every family.

I became a pediatrician to pursue my passion for helping families raise healthy children. My secondary education began at Binghamton University where I earned a B.S. in Biology. I
attended medical school at New York College of Osteopathic Medicine at New York Institute of Technology and then completed my pediatrics residency at Cohen Children’s Medical Center of Northwell Health. I am board certified in pediatrics and have special interests in breastfeeding medicine and nutrition. I am a board certified lactation consultant.

In addition to practicing medicine for over 10 years, I teach parenting classes and author a medical blog for parents: DoctorMom.blog. My blog is a great way for me to answer commonly asked questions by my patients, friends, and families. I try to transform complicated medical subjects into easily readable posts for busy parents.

Outside of work, I am a mom of three active children (and a puppy) that keep me very busy! As a family we love outdoor activities including hiking, skiing and going to the beach. In my spare time, I enjoy reading and playing tennis. My journey as a parent has had a huge influence on how I practice medicine.

I am so excited to be a part of the Happy and Healthy team. We have a shared vision of providing both the highest quality medical care and guidance towards wellness to our patients and their families.

Originally from Queens, NY, I spent 10 years living in Texas getting my education.  I graduated Southern Methodist University magna cum laude with a Bachelor of Science in Biology and a Bachelor of Art in Chemistry.  After two years of performing cancer research, I went to the University of Texas Medical School in San Antonio.  I graduated a member of Alpha Omega Medical Honor Society.  I completed my pediatric residency at NY Presbyterian Weill Cornell Medical Center.  For the last ten years, I have served as a clinical assistant professor of pediatrics at a local community health center in the Bronx, NY. I am a board certified pediatrician.

My love for children and my aspiration to become a pediatrician started in my own childhood.  I enjoy forming bonds with my patients and families, watching them grow and thrive. I am passionate about teaching families healthy lifestyles, arming them with knowledge to help prevent chronic diseases of adulthood.  

My hobbies include travel, cooking and watching my infant daughter discover her world.  She is active and a bright spot in my day.

I am excited to join the Happy and Healthy Pediatrics family.

MD  FAAP

I received a bachelors in arts from New York University, majoring in biology.  I obtained my medical school training at Mount Sinai Medical School in Manhattan NY and completed my pediatric residency at Montefiore Medical Center in Bronx, NY.

I have worked as a general pediatrician for the past 23 years. The majority of that time was spent in community health   I worked first for 13 years at Neighborhood and Family Health Center in Bronx New York and then at Ryan Health Women and Children Center as the Assistant medical director and pediatrician.  I trained medical students from the Sophie Davis Biomedical program, an accelerated BS/MD program and nurse practitioner students from Columbia and Pace Universities at both sites. I also provided clinical oversight for the School Based Health centers.

Being a pediatrician has allowed me to follow my passion in helping children. As a pediatrician you have a big impact on the lives of children and their families by growing with them and helping them improve their physical, mental and emotional health by making healthy lifestyle decisions. 

I enjoy spending time with my family and friends.  My hobbies include playing music, violin and piano, learning new languages and volunteering.

MD FAAP

I started my journey to become a pediatrician at CUNY Brooklyn College as part of the B.A/M.D. program, and the Macaulay Honors College. I graduated summa cum laude with a Bachelor of Arts in Business Administration with honors and a minor in chemistry. I continued to medical school at SUNY Downstate in Brooklyn, NY. I completed my
residency at Northwell Cohen Children's Medical Center in New Hyde Park.

For as long as I can remember, the type of doctor I wanted to be was a pediatrician. I enjoy helping children grow and develop, in
partnership with parents, to make healthy choices, and to build a bright future. I want to arm kids and families with knowledge, and
empower children to take charge of their health.

In my free time, I like to have fun and spend time with family and friends. I also like to watch movies, sing and dance, solve puzzles,
do arts and crafts, and bake.

I am very happy to be part of the Happy and Healthy family.
