Our sponsors

GRIN Europe is delighted to introduce you to our sponsors who are helping us make the Fifth European GRIN conference a reality. 

We give our thanks to:

GRIN Therapeutics,  Platinum Sponsor

The Barcelona San Joan De Deu Children´s Hospital for providing the conference venue, IT services and Zoom channel free of charge.

Conference venue

The venue for our Fifth European GRIN Conference, the San Joan de Déu Hospital is located at:

Passeig San Joan de Déu 2
08950 Esplugues de Llobregat
Barcelona, Spain

As in previous years prior to the Covid pandemic, we have once again chosen the San Joan de Déu Hospital as the venue for our conference. The San Joan de Déu Hospital is a renowned and highly specialized children’s hospital that is home to most of the European Reference Networks (ERN’s) for (rare) disorders. 

In close cooperation with the Barcelona GRIN Team, the doctors at the San Joan de Déu Hospital have been treating children with GRIN disorders for the last 9 years and have built up considerable expertise in this area. The hospital is consequently a center of excellence and an important hub for research into GRIN disorders. 

Since the very start of GRIN Europe, the San Joan de Déu Hospital has been a very loyal sponsor of the European GRIN Community and we are very honored and thankful that they have once again provided GRIN Europe with the venue for our Fifth European GRIN Conference and with all the online services needed for live streaming and recording for our conference.
