I'm a field collector from Ottawa, Canada.
I also enjoy photographing my finds.
I volunteer at the Canadian Museum of Nature working with the national mineral collection under the direction of the curator Michael Bainbridge and research scientist Inna Lykova with whom I have co-authored two articles in Rocks&Minerals.
I am a founding member and the current President of the newly formed (incorporated 2024) Ottawa Valley Mineral Club.
