Dr. Yazdi first took employment for three years at Valley Hospital as a house Pediatrician. In 1997 she joined a large group practice with offices in Fairlawn, Mahwah and Pompton Plains, New Jersey. Disappointed with being in a big practice and not building rapport with families, she left in January 2004 to start her own practice in Wyckoff. Dr. Yazdi enjoys practicing medicine in an environment where she knows all of her patients and their families. 
Dr. Yazdi has received NJ Top Doc, Most Compassionate Doctor and Patient's Choice award consecutively since 2008.  She remains in NJ Top Pediatricians in New Jersey magazine. Her husband is an IT Director at Toys R Us in Wayne. They have a daughter and a son and live in Franklin Lakes.

Dr Erin Leonard, DNP,PB-C,APN,EDD,MSN

Dr. Leonard graduated from University of Vermont with a degree in nursing (BSN).  After two years working at Memorial Sloan Kettering in NYC she went back to NYU and obtained an Advanced Practitioner Degree in Primary Adult Care.  Erin worked in cardiothoracic and pain management for several years before deciding to change to pediatrics.  She attended Seton Hall University and obtained her doctorate in Pediatric Medicine in 2010.  Her residencies included Pediatric Endocrinology at the Molly Center HUMC and Pediatric Pulmonology at Rutherford Pediatrics.  While raising her four children Erin worked as a Maternal Child float APN at Valley Hospital.  Erin decided that teaching at the college level and working as a Pediatric Primary Care Provider was the perfect combination and accepted a faculty position at Seton Hall University in the College of Nursing.  Erin has taught Pharmacology, Pediatrics Adult Health and Human Development.

Erin is published in the Irish Journal of Lactation and is pending publication in the U.S.  She has a special interest in Maternal Child lactation and the transition parents go through when bringing a new baby home.  Erin has over 2000 hours of lactation experience and is up to date with the latest recommendations from the World Health Organization and Healthy People 2020 initiatives.

Erin has had a relationship with Dr. Yazdi for the past 15 years and when Wyckoff Pediatrics transitioned in 2017, she joined the practice while continuing to hold a faculty position at Seton Hall.  She and her husband James, a financial broker, live in Glen Rock with their four children.

Dr. Leonard is a Board Certified Pediatric Practitioner and Adult Internal Medicine Practitioner.  Erin's experience as an RN has made her transition to Doctor extremely smooth with very personal approach.


We are fairly new to the area and were lucky enough to have found Dr. Yazdi and Dr. Torres for our children. We had the pleasure of meeting with both of them on separate occasions and have found that they are very compassionate, caring, understanding physicians. We have since moved, but we will definately keep Dr. Yazdi and Dr. Torres as our pediatricians!
Cynthia - 2017

We switched Pediatricians September 2010. Since our transition, Dr. Yazdi has seen my daughter several times. She has been very professional, helpful, kind and knowledgeable with our daughters illnesses. If you call the office, the staff is always so helpful and the nurses are wonderful. Also, Dr. Yazdi always calls you back if you need to speak, she is a sweet heart! The office staff is remarkable and environment is very clean. Its important to keep an office clean when you have sick kids coming in and out, they do a great job! Our daughter gets hugs from Dr. Yazdi, and this puts a smile on our face.  We feel very comfortable with our decision in picking Mondana Yazdi M.D. Wyckoff Pediatrics .
Renee A. - 2017

At this point the individual who was diagnosed will be out of the school building until she/he is cleared by a physician. Pertussis is a highly contagious disease that is spread through the air by a cough or a sneeze.
