- On 13th October 2016 stem4 attended the Positive Practice in Mental Health Awards – these are very prestigious national awards and stem4 was nominated in two categories. We won the Digital Innovation award for the Calm Harm app, and our founder/CEO Dr Nihara Krause won the Making a Difference award. We would like to thank our sponsors, ambassadors, volunteers and trustees for all their support, allowing us to move ahead in the digital world and helping us to make a difference in our followers’ lives.
