Alex L. Cross-Knorr PhD

When working with families, my goal is to combine my expertise in child development and behavior with parents’ expertise on their child and family to find effective solutions. I seek to help diverse families address their children’s behavioral and emotional needs in ways that work for them, as a crucial part of their children’s overall health. I take a non-judgmental approach that incorporates a family’s background, culture, values, and goals to find the best path to helping their children thrive.


Growing up, Dr. Cross-Knorr always enjoyed working with children as a babysitter (including for her three younger siblings), camp counselor, and Sunday School teacher. Once she started taking psychology courses at Williams College in western Massachusetts, she knew she wanted a career in child psychology. Dr. Cross-Knorr went on to pursue her doctoral degree in clinical psychology at Temple University in Philadelphia. As part of her studies, she completed some of her clinical training at Nemours A.I. duPont Hospital for Children in nearby Wilmington, Delaware, and became hooked on working in a healthcare setting. Dr. Cross-Knorr first worked in a pediatric primary care office during her clinical internship at WellSpan Health in York, PA. She then returned to Nemours to complete a postdoctoral fellowship focused on pediatric primary care psychology and stayed on as a primary care psychologist before moving to Portland.

Some of Dr. Cross-Knorr’s specific areas of interest include helping families navigate the toddler and preschool years, helping kids and teens manage anxiety, evaluating and treating ADHD, building healthy sleep habits, and working together with pediatricians to address GI issues such as abdominal pain, IBS, and constipation. She practices in our Portland office.

East Coast Native with a West Coast Heart

Dr. Cross-Knorr is a third-generation native of the New York City area and has lived on the East Coast her entire life (New Jersey, Massachusetts, Washington, DC, and Philadelphia to be exact) before moving to Portland. Soon after meeting her husband, a Seattle native, she realized that her laid-back, stop-and-smell-the-roses personality was probably better suited to the West Coast. Although she may miss the rich history and “grit” of Philadelphia, she is looking forward to spending lots of time outside and the friendlier sports fans.

Arts Lover

Dr. Cross-Knorr played the piano and flute through college and grew up listening to all generations of music, attending Broadway shows, and visiting lots of museums. She took many types of dance classes growing up and even did some acting in low-budget plays in her family’s basement (she chose to take her talents to the orchestra pit for her high school’s annual musicals). These days, Dr. Cross-Knorr enjoys attending concerts, dance performances, and musical theater and still takes ballet classes.


Dr. Cross-Knorr and her husband, a pediatrician, are currently expecting their first child. They are looking forward to gaining some real-world experience (and likely a strong dose of humility) for their knowledge of children and parenting, along with someone to share their love of Disney movies.

Fun Facts

Dr. Cross-Knorr enjoys trivia and has auditioned for the game show Jeopardy. She did not get called onto the show yet, but plans to keep trying! 

Dr. Cross-Knorr and her husband enjoy traveling, hiking, camping, cooking and baking, exploring restaurants (especially for Mexican food, Thai food, or a really good burger and fries), and attending as many baseball games as possible, even if they root for different teams (fingers crossed that those rumors of a major league team in Portland come true!). So far, Dr. Cross-Knorr’s favorite Oregon hike is Ecola State Park on the coast, but she is excited to explore more hiking and camping spots around Portland - suggestions welcome!

Dr. Cross-Knorr is really looking forward to collaborating with the excellent PANW team and learning from each other so we can help kids and families lead healthy, happy lives!
