During the Coronavirus Pandemic, Childrens Medical Group remains open and is here to keep our patients healthy. Our office remains open and ready to care for our patients. Well visits are available in the mornings and some early afternoons, while sick appointments are available in the afternoons and later afternoons. We want you to know that we are Committed to Patient Safety: The safety and well-being of our patients, families, and staff is our highest priority. We understand there may be feelings of apprehension coming into our office, but want to assure our patients and families of the measures we are taking ensure everyone’s safety. We no longer have patients wait in the waiting room, but instead work hard to get patients roomed as they arrive for their appointment. Any patient with fever or symptoms of illness are asked to reschedule their appointment. Patients are screened prior to any sick visits being scheduled. When reasonable to do so, sick appointments may take place by video visit. We continue to clean rooms in between patients, with “deep cleanings” occurring nightly. All patients over 2 and parents must wear a face mask when coming to the office. We ask that you do not bring anyone extra to the visit and only one parent accompany their child to their appointment.


Welcome to our Practice

Childrens Medical Group offers comprehensive care for infants, children and teens. Because we are a smaller private practice, we really get to know our patients and families well. We practice medicine in a setting where we can watch our kids and their families grow. We have an amazing team that works hard to make each and every visit to our office a positive experience.

Whether it's a check up or sick visit, your first visit or if you've been a long time patient, we strive to make sure you and your children are always comfortable and informed. We take the time to talk with parents to help you understand your child's needs, and equip you with the knowledge necessary for promoting a lifetime of health and wellness.

Our pediatricians believe exceptional care is a must, and it's achieved when there is an on–going relationship between us the doctor, your children the patient, and you the parents. We want to be lifelong partners in your child's health and we achieve this by listening to your questions and concerns, and educating you on how to promote a healthy lifestyle for the entire family.

When you choose us to care for your children you can feel confident that you are in great hands, partnering with knowledgeable, compassionate doctors who have dedicated their careers to child–focused health care. Please do not hesitate to contact our office with questions or concerns. Our wonderful pediatricians and staff look forward to meeting you and your family.

"We love Dr Monahan and all of her staff. She has been my children's doctor for 15+ years."

- Jadette L


"Dr. Rosenfeld is a Blessing to her patients and their families. She is a caring, kind and brilliant doc. All 3 of my children were patients of hers for years. We were all devastated when they turned 18 and it was time for them to move on. She was always available during and after hours to speak to. She spent me to answer all of our questions. Her diagnosis was always right on. She’s a gem. One of the best doc’s I’veseen. Blessings."
