Meet the BUSNA Board
Christine Griffith

Christine is a proud graduate of Penn State University. Prior to being diagnosed with Birdshot she held positions at various financial services organizations and served as a preschool teacher at a local church. Christine is particularly proud of being a mother to her grown children, and in her free time enjoys traveling, volunteering and outdoor activities.
In 2019, Christine co-organized Birdshot Day in Philadelphia, which was attended by patients from seven different states and included a Q&A session with Dr. Dunn as well as presentations from experts on topics such as nutrition for inflammation and advances in artificial intelligence to help treat eye disease.
She is passionate about working with the board of BUSNA to provide awareness of Birdshot Uveitis and to support both newly diagnosed and long-term Birdshot patients.
Andrea Munk
Andrea Munk, a resident of Marlboro, New Jersey, is the Assistant Treasurer of Birdshot Uveitis Society of North America.

Mari Schlorff
Mari Schlorff, living near Barrie in Ontario, Canada, is a founding board member of the Birdshot Uveitis Society of North America.
Mari was diagnosed with Birdshot Uveitis in 2007 in her home country of Scotland after reaching out to her late mother’s birdshot specialist in Aberdeen. She has been receiving excellent care since diagnosis from Dr. Larissa Derzko, Uveitis specialist in Toronto Canada.
Mari is a retired physiotherapist, having worked in many clinical settings in Scotland, South Africa and Canada. She and her family enjoy several outdoor pursuits including sailing, golf and trail walking.
She has seen firsthand the potentially devastating vision loss of Birdshot Uveitis. Her mother was diagnosed in 1985, and she later became legally blind. Mari’s role on the board is to lend a voice from a Canadian perspective, supporting the Society and board members in many activities.
She congratulates the board on its passion, work ethic and determination in establishing this not-for-profit society to help other patients across North America as well as globally. Mari is excited to see what lies ahead in the journey toward finding a cure for Birdshot Uveitis.
Leanne Oswald
Leanne Oswald, who lives in the Lehigh Valley, Pennsylvania, was first diagnosed with Birdshot Uveitis in May of 2003, at 39 years old.
As a registered dental hygienist, a mom to a very busy middle school daughter and elementary school son, and a wife to a busy CPA, Leanne has often wondered if Birdshot would cause the end of her career and limit her ability to keep up with her children’s schedules.
Thankfully, after 11 years of various doctors and treatments, she found Dr. Jennifer Thorne at Johns Hopkins Wilmer Eye Hospital. Dr. Thorne’s treatment plan has been very effective at stabilizing her Birdshot symptoms and vision. Eighteen years after her diagnosis, Leanne is very thankful to still be working part time as a dental hygienist and to be able to drive (daytime only).
Leanne serves on the board of BUSNA, where she is involved in various activities and committees. She is also an admin on the International Birdshot Uveitis Society FB group, and she has attended Birdshot days in London, Baltimore and Philadelphia.
Leanne appreciates these wonderful groups that share vital knowledge, support and friendship!
Liz Cohen
Liz lives in Nashville, TN. She is the newest member of BUSNA’s Board.
Liz first noticed fleeting visual disturbances in 2016. It wasn’t until 2108 that more bizarre symptoms sent her to a neuro-ophthalmologist who diagnosed her with “visual migraines”. After her birdshot diagnosis in 2019, she began aggressive treatment with prednisone and immunosuppressant medications. Her eyes have been quiet for the past year.
Inspired by her 100-year-old mom, Liz stays very active. She’s an engaged member of her temple, Kol Dodi, in Nashville. She also belongs to a book club and walks each day, often with Jasper, her dog.
A native New Yorker, Liz has worked in sales and credit in the building management field. Her responsibilities have included some of Manhattan’s most beautiful and iconic buildings.
Liz is honored to join the board and believes strongly in what she sees as the threefold purpose of BUSNA: to fund research, to share information and data, and to support each other.
Josette Abruzzini
Josette Abruzzini lives in Lake Winola, Pennsylvania. She is a founding member of
BUSNA and serves on the Board as our Blogger and Secretary.
In early 2019, Josette noticed floaters in her vision and a sensitivity to glare. She was soon diagnosed by retinal specialist Dr. Randall Peairs of Northeast Eye in Scranton, PA. She is grateful to Dr. Peairs for inspiring her to do everything possible to improve her birdshot situation.
She’s currently being treated by uveitis specialist Dr. Vincent J. Baldassano of Geisinger Eye Institute in Danville, PA. Thanks to a speedy diagnosis and additional guidance from an Integrative physician in New Jersey, Josette’s treatment has consisted of occasional Kenalog injections and a broad array of anti-inflammatory dietary and supplemental protocols.
A native of Newfoundland, Canada, Josette has lived in the US since her college days. She is a retired educator, having taught both elementary music and 5th grade STEM. She is currently honing her writing skills and hopes to someday publish a book.
As writer of the BUSNA blog, Josette works to bring awareness to issues surrounding Birdshot Uveitis. She is encouraged by recent advancements in research and believes that each person can make a difference in their own health and in helping researchers find a cure.

Meredith Cross
Meredith Cross is a partner at the law firm Wilmer Cutler Pickering Hale and Dorr LLP (WilmerHale). Her practice focuses on securities and corporate governance law, including counseling public companies and their boards on Securities and Exchange Commission (SEC) disclosure and other requirements and advising on defense of SEC enforcement investigations. In her 40 plus years of practice, Meredith has held numerous positions at the SEC in the Division of Corporation Finance for a combined total of 11 years, including Chief Counsel, Director of International Corporate Finance, Deputy Director and Director. In her most recent time at the SEC, Meredith left WilmerHale to return to the SEC in the wake of the financial crisis in 2009-2013 as Director of Corporation Finance. In that role, she frequently testified in Congress on behalf of the SEC and was responsible for a staff of approximately 500. In 2019 Meredith and her husband, John, moved to the Connecticut shore after 30 years in Washington, D.C., to be near their son and grandchildren, and she transferred to WilmerHale’s New York Office. She continues to have a very busy client practice and is involved in many activities related to securities law and the SEC, including chairing national securities law conferences and serving on the Board of Trustees and as President-Elect of the SEC Historical Society.
Meredith was diagnosed with Birdshot in the Spring of 2012 by Dr. Jennifer Thorne at the Wilmer Eye Institute at Johns Hopkins. Concerned that there was insufficient focus on Birdshot research in the U.S., Meredith and her family dedicated significant resources to raising the profile of Birdshot at Wilmer Eye, including establishing the Birdshot Research Fund at Wilmer Eye. Meredith, John and their son, Joseph, endowed the Cross Family Professorship in Ophthalmology (focused on Birdshot and other forms of Uveitis) at Wilmer Eye so that there would be more permanent funding for research of this rare condition. Dr. Thorne is the inaugural Cross Family Professor, and Meredith continues to travel to Baltimore for treatment from Dr. Thorne. Meredith and John serve on the Board of Governors of the Wilmer Eye Institute. She notes that it is just coincidence that she has two very important “Wilmer’s” in her life – there is no relation.
