Julia W. Mason is an American pediatrician active in the anti-transgender “gender critical” movement.
If you are the parent or guardian of a gender diverse young person, do not take your family member to Mason for care. If you are a minor being forced to see Mason by unsupportive adults, do what you can to end treatment with Mason and seek out supportive local resources instead.
Background
Julia Robin Winter was born on March 19, 1966. Mason married Eliot C. Mason (born 1967).
Mason attended University of Illinois, earning a master’s degree and a medical degree in 1994. Mason did residency training in Pediatrics at Children’s Hospital Los Angeles from 1994 to 1997. Mason is licensed in Oregon, California, Minnesota, and Wisconsin. Mason is a board-certified pediatrician, a Fellow of the American Academy of Pediatrics, and currently practices at Calcagno Pediatrics in Gresham, Oregon.
Anti-transgender activism
Mason is involved with anti-trans organization Society for Evidence-Based Gender Medicine (SEGM). According to Mason, most gender diverse youth seen at Mason’s practice have “neurodevelopmental challenges or psychiatric comorbidities.”
AAP Resolution 33 (2021)
Introduced at the AAP Annual Leadership Forum 2021, this resolution “registered concern about the low quality of evidence underpinning treatment of minors with hormones and surgeries.”
AAP booth cancellation (2021)
SEGM tried to register a booth at the AAP conference in 2021, but it was rejected. Mason wrote the letter protesting the decision.
AAP Resolution 27 (2022)
Mason and four other pediatricians drafted Resolution 27 critical of AAP’s consensus on best practices for gender diverse youth. The authors are:
- Julia W. Mason (Gresham, Oregon)
- Sarah B. Palmer (Carmel, Indiana)
- Paula Brinkley (Berkeley, California – Stanford Children’s)
- Debra Hendrickson (Reno, Nevada – Northern Nevada Pediatrics)
- Patrick K. Hunter (Milton, Florida – Pensacola Pediatrics)
AAP Resolution 37 (2023)
Mason again attempted to draft a resolution in 2023, which Mason claims is sponsored by 23 FAAP coauthors.
Wall Street Journal opinion and AAP response
Mason joined fellow anti-trans activist Leor Sapir in attacking mainstream pediatric organization American Academy of Pediatrics (AAP) for supporting gender affirming care for youth. In response, AAP President Moira Szilagyi stated:
Gender-affirming care can be lifesaving. It doesnât push medical treatments or surgery; for the vast majority of children, it recommends the opposite.
This isnât the story that is being told by anti-transgender activists. No European country has categorically banned gender-affirming care when medically appropriate. Contrary to what Dr. Mason and Mr. Sapir claim, the U.K. isnât moving away from gender-affirming care. It is moving toward a more regional, multidisciplinary approach, similar to what is practiced in the U.S.
Mason frequently appears with other conservative and anti-trans activists, including:
- Zhenya Abbruzzese
- Erica Anderson
- Stephen Beck
- Benjamin Boyce
- Joey Dumont
- Paul W. Hruz
- Megyn Kelly
- Stephen B. Levine
- William J. MaloneÂ
- Stella O’Malley
- Leor Sapir
