and approach

Dr. Weiss is recognized in her field and by her clients for providing empathetic, results-driven psychotherapy and careful and comprehensive psychodiagnostic evaluations that get to the correct diagnosis the first time.   Dr. Weiss’s approach stems from her belief that optimal results come from working collaboratively with clients, families, teachers, and other treating professionals to generate treatment plans appropriately tailored to individual clients.  No two clients are alike, and no two issues are the same.  Likewise, Dr. Weiss believes that there are no shortcuts to accurate psychodiagnosis. Dr. Weiss spends several days with each client and always observes elementary school clients in classroom settings.  She takes the time necessary to investigate and understand each client’s learning styles, social and emotional factors, and academic challenges.  That’s why leading academic institutions across Los Angeles and elsewhere trust and rely on Dr. Weiss’s recommendations.  For the past 20 years, Dr. Weiss has successfully applied this approach to help clients realize their cognitive potential and overcome seemingly intractable challenges, including anxiety, perfectionism, depression, ADHD, autism, executive-functioning challenges, self-esteem issues, life transitions, and overwhelming academic stress.    


and training


Dr. Weiss has a  Ph.D. in Clinical Psychology from the California School of Professional Psychology (CSPP), a master’s degree in counseling psychology from Boston College, and a master’s degree in clinical psychology from CSPP.  She received her undergraduate degree from Boston University, where she graduated cum laude with distinction.  Dr. Weiss is also a proud graduate of the Harvard-Westlake School.  By virtue of this experience, Dr. Weiss brings a first-hand understanding to the academic pressures many of her clients face in private preparatory schools.  Dr. Weiss has worked with hundreds of students enrolled in both Los Angeles private and public schools.   

Dr. Weiss’s clinical training and experience includes providing therapy for children and families, running parenting groups for parents of teens, leading teen groups in high schools, providing individual therapy in an elementary school, providing individual therapy and community outreach at Wheaton College Counseling Center in Massachusetts, leading a teen girls group in a private practice, and a pre-doctoral internship in an inpatient psychiatric hospital where she treated children, teens, and adults.  She also conducted psychoeducational testing in a college learning resource center.  Dr. Weiss’ doctoral dissertation on relational aggression in girls was selected for presentation at the American Psychological Association’s annual convention, a rare honor given to a select few researchers.  While completing her postdoctoral training, Dr. Weiss gained extensive experience conducting psychodiagnostic evaluations of students with ADHD, autism, and other learning challenges, including so-called “twice exceptional” clients.


Outside of clinical practice, Dr. Weiss is active in both professional and non-profit organizations.  She served as president of the California Psychological Association of Graduate Students (CPAGS) while also serving on the Board of Directors for the California Psychological Association.  At present, Dr. Weiss serves on the Board of Directors for Builder Bees, a non-profit organization that provides programming for girls of all abilities, and on the Advisory Board of the Well Baby Center , a nonprofit parenting and counseling center.  Dr. Weiss also enjoys mentoring students at her alma mater, the Harvard-Westlake School.


In her free time, Dr. Weiss enjoys doing art projects with her two young children, building Legos with her daughter, knitting, playing soccer with her son, traveling with her husband, and baking.  She also enjoys spending time with her shih-tzu, Lucy, who occasionally accompanies her to the office.
