Dorothea Sandra

I am a successful polymath painter. I paint in different art categories, and from France to Hong Kong, my art has sold nationally and internationally. With my florals, I have become known as The Artist of Happiness. I am evidence-based design-certified, and I use medical/scientific study results to create art that triggers the brain to release happiness-related (dopamine) chemicals. In 2024, I was interviewed by a brain research team at Johns Hopkins University School of Medicine for my art and my book, 100 Days Of Happy Happy Art, Evidence-Based Design. In 2024 and 2025, my art was featured in Healthcare Design Magazine. I am also the creator of the Smart City Art Collection, which features abstract art pieces promoting smart and sustainable cities of the future. 101 of my pieces are currently in international curations in Spain, Belgium, France, Germany, the United States, and more. In 2026, I received the honor of painting for three months in beautiful Shanghai, China, at the Swatch Art Peace Hotel. I am currently working on a new abstract art series called the God of Gold series.

I come from a generational arts family, and I was professionally trained as a child.

My Smart City Art series was featured at the 2025 SRI Sustainability Research and Innovation International Congress, held at the Sheraton Grand Riverwalk in Chicago. My art is currently in 101 international art curations. I also received the great honor of painting at the Swatch Art Peace Hotel, Shanghai, China for 3 months in 2026.
