Be a part of something profound.
GRAPPA is an amazing network of people interested in psoriasis and PsA.
Through your involvement you can share ideas, collaborate on research and lead projects aimed to improve the lives of people living with psoriatic disease.
What makes GRAPPA so special to me? What really is unique to me when thinking about GRAPPA in comparison to other similar organisations is - besides the international scientific exchange - the interdisciplinary collaboration between dermatologist and rheumatologist aiming to improve the knowledge about psoriatic diseases, ultimately resulting in optimizing the care of our patients!

Rheumatologist and GRAPPA Steering Committee Member
GRAPPA is an incredibly welcoming and inclusive organisation. From the moment I attended my first meeting in 2009 I felt encouraged to participate and contribute and this ethos remains very much alive in all the activities from the annual meeting to young-GRAPPA.

It has been fascinating to be a part of GRAPPA, and see how much progress has been made in the ability to provide therapeutic options with patients with Psoriatic Arthritis. GRAPPA is a dynamic and collegial community, where we all learn from each other

M.D., Rheumatologist and GRAPPA Co-Vice President
GRAPPA celebrates 20 years and growing in 2023. In that 20 years, GRAPPA has become the go-to organisation for those interested in Psoriatic Disease. With the involvement of all the key players (rheumatologists, dermatologists, basic scientists, patient and industry partners), the strengths of the GRAPPA educational and research programmes are truly impressive. As GRAPPA co-president, I really enjoy both the social and academic contacts and stimulus which GRAPPA provides.

About Us
Originally inspired by the Assessment in Ankylosing Spondylitis Working Group (ASAS), GRAPPA was formed in 2003. GRAPPA has pulled together many different groups, including preeminent researchers and thought-leaders in psoriatic arthritis (PsA) and psoriasis (PsO).
In 2015 a team of Patient Research Partners was added to round out our perspective. The idea was to form a consortium of rheumatologists, dermatologists, radiologists, epidemiologists, patient representatives and others who would like to contribute to the field of PsA. At the inaugural meeting in 2003, a consensus exercise started the group toward prioritizing domains of inquiry in PsA and PsO.
Subsequent annual meetings have focused on identifying and initiating research projects, advancing standardized criteria for psoriatic arthritis registries, and developing treatment guidelines for PsA. GRAPPA is a 501(c)3 nonprofit organization with offices in Seattle, WA and members from around the world.
