What parents say about Dr. Larsen

“We were referred by my husbands brother, who's two grown daughters were patients of Dr. Murphy since they were children. Our son was 6 weeks old when we decided to give Uptown Pediatrics a try. By far it has been the best experience! I immediately had my other two children's medical care transferred over as well. They have been nothing but helpful and informative from the very beginning. The front desk has never given me a hard time, even when I request documents at the very last minute, they are always prompt. The medical assistants are caring, lovable and patient, even with my toddler. We are never turned down for an appointment, even when we have had last minute emergencies or concerns. Dr. Murphy was my children's doctor, until his unfortunate passing. We have switched over to Dr. Larsen. But honestly it does not matter which doctor treats my children, because they are ALL wonderful. The entire staff has been nothing but incredible to me and my family and we will continue to receive their care, until all of my children are adults : )”
