Dr. Siggú, full name Sigrún Mjöll Halldórsdóttir, completed her PhD in Food Science from the University of Iceland in 2013. In parallel with her studies, Siggú worked at Matís as a specialist and project manager in the Biotechnology Department for about 10 years. She also completed a large part of her Master's degree in Law at Reykjavík University, where she specialized in Intellectual Property, and worked as a specialist in the Intellectual Property Department of Matís together with the company's deputy CEO. Siggú represented Iceland on the Council for Scientific Conferences and attended numerous conferences abroad and domestically. She has written a number of peer-reviewed scientific articles and patent applications. She held the position of Adjunct Professor at the University of Iceland for a time, where she taught Food Chemistry, as well as being a supervisor in a Master's degree program in Food Science.

Siggú graduated as an ICF Life Coach from the Evolvia Coaching Center in 2018 and will graduate as a Massage Therapist at Fjölbrautarskólann in Ármúli at the end of 2025. Siggú is a fitness competitor and competed in IFBB model fitness +35 in 2018 in Reykjavík, NPC model fitness +35 in 2019 at Open Iceland, IFBB figure fitness +35 in 2021 in Akureyri and NPC wellness fitness +40 in 2023 in Ringsted, Denmark.

Through coaching and consulting, Siggú uses her knowledge and experience to help others achieve what they want in their lives, with a special emphasis on lifestyle and mindset. Through massage therapy, she helps people release muscle tension, soreness and innflamation, relax and enjoy.

“I have learned that anything is possible, and I mean ANYTHING. I have accomplished incredible things in an incredibly short time. With certain mindsets and habits, I have managed to achieve all the goals I have set for myself over the years. When one goal is achieved, another takes over, and so on and so forth, so it is never truly “done”. That is how I have learned how important it is to enjoy the journey. To enjoy is a form of art that one must master. Life is to enjoy and create.”

There was an interview with Dr. Siggú in Smartland around Christmas 2019, where she describes how she achieved all the goals she set for herself in 10 years. See the interview.
