About Andrea Mertz

Dr. Andrea Mertz, MD, is a Texas native and moved to Colorado in 2013 after completing her residency in pediatrics in Cleveland, Ohio. As a pediatric specialist, Dr. Mertz addresses the physical, mental and social health of children from birth to young adulthood.

She loves practicing medicine because the field blends working with people, building relationships, and using clinical skills to solve problems. Becoming a pediatrician was a perfect fit for Dr. Mertz, as she always wanted to work with kids and families.

“I love seeing patients of all ages, from newborns in the hospital to teenagers about to leave for college,” says Dr. Mertz. “Kids keep me on my toes and make me laugh; I love working with them.”

As a new mom of twins, Dr. Mertz is going through the same sleepless nights and the many challenges new babies bring.

Her hobbies include yoga, skiing, and getting outside as much as possible with her husband, twin boys, and dogs.

She welcomes patients from all across the North Metro Denver and Boulder areas, including Arvada, Golden, Lafayette, Louisville, Superior, Broomfield, Boulder, Westminster, Erie, Brighton, Firestone, Frederick, Thornton, and Northglenn.

Specialty Areas

Dr. Mertz provides a full range of pediatric services including:

• General pediatric care including well-child exams and physicals
• Newborn and well-baby care
• Same-day sick child visits
• Immunizations
• Sports physicals

“I believe in treating the entire family,” says Dr. Mertz. “Although I always consider the needs of my young patients first, having the family on board for treatments and preventative care is important when it comes to successful outcomes. I also believe in being a good steward of our medical tools, which includes using antibiotics only when necessary and sending for lab tests only when needed.”
