I am a board-certified pediatric nurse practitioner specializing in primary care, providing a well-rounded and compassionate approach to pediatric medicine. I have always called pediatrics home. Through the years it has been a true pleasure to watch my patients grow, develop, and achieve life milestones. Motherhood has taught me the importance of having a provider who listens to the child and family, is caring, and is focused on their healthcare needs. It is my commitment to provide extraordinary care as a primary healthcare provider for you from birth to 21 years of age.
My little something extra
Being born and raised in South Louisiana, it is a true honor to care for children and families in this community and its surrounding areas.

Y'all need to find more practitioners like Martha Cossich. She goes above and beyond for her patients. She has helped us when nobody else could get us answers. She has even fixed other people's mistakes such as the urgent care. She definitely needs the recognition she deserves.

Dr. Martha always addresses all of our concerns and the staff that we see before we see the doctor is always very friendly and super helpful. We truly feel like family when we visit Manning Children's Family in Slidell. And Dr. Cossich is always listening and giving us clear directions and advice as well as providing her own personal experiences. That makes it feel more personable and easy to understand.

Mrs.Martha is so good!! She literally treats my daughter like her own. She answers all of my questions, and goes in depth when explaining to make sure I understand everything. She makes me and my daughter feel comfortable. No matter how small my question is or maybe even irrelevant to what's going on at the time, she answers it and makes me feel like it's ok to ask. I can't say enough good about her.

Did not see the MD I had went on the portal to see. Instead it was a NP. She was very nice but I wanted to see who I chose on the portal. Very misleading. You should see who you click on.

Northlake Pediatrics was the absolute most amazing doctor. We switched over two or three years ago. They were very thorough, very, very detailed. They took their time. They spent each, they did each kid separately and did what they were supposed to do individually. They was very thorough and I will definitely be back and I will keep my children there until they're too old to go there. I highly, highly recommend them and that doctor is absolutely phenomenal.

The provider was awesome with all 3 of my children, [patient name], [patient name] and [patient name]. She answered every question that [patient name] had about his body and things that he needed to know and everything for [patient name] as well. So everything was great.
