Jack RobertsonPresident – Jack has been interested in his Scottish heritage since he was a teenager. He is a member of Clan Donnachaidh (Robertson), and you’re likely to see his own Robertson clan wearing their tartan at USCO events. He has been married over 20 years to his sweetheart, Heather, and has three children. Jack is obviously a fan of history, as he works for the Oklahoma Historical Society in the State Historic Preservation Office.

Paul Sinclair Vice-President – An Oklahoma native of Irish/Nordic descent, Paul has always had a fierce love for his Celtic ancestry. As an adult he delved into the world of piping, and he is part of the state’s largest and most active pipe band, the Oklahoma Scottish Pipes and Drums. When he’s not enforcing his “no piobaireachd”  rule with the pipe band, Paul is a police officer with the Edmond Police Department and has been in law enforcement his entire adult life. In addition to serving on the USCO Board, he is also the piping director for the Iron Thistle in Yukon. Need to find him? Just follow the pipes.

Tammy McCauley – Treasurer – Tammy managed the Children’s Glen at the Iron Thistle. She loves Pina Coladas and getting lost in the Scottish rain (in Scotland, and Ireland – shh). She is Scottish (Clan Wallace), Native American, and a mesh of other nationalities. Tammy is all but dissertation in her doctorate, Educational Leadership in Curriculum and Instruction. She is a teacher, wife, and mother.

Kristi Kime – Secretary – Kristi is a member of both Clan Donald and Clan MacIntosh. In addition to her skills at generally keeping us organized, she is a piper for Oklahoma Scottish Pipes and Drums and makes a mean Irish Car Bomb Cupcake. Don’t worry, though, the only thing exploding will be your taste buds.

Martha Hixon – Chief Programs Officer – 

Jennie Stephens – Chief Development Officer – Jennie is a mother of 3 grown children and 7 grandchildren with 1 great grandson. She has been happily married to her husband Paul for over 20 years. Her interest in Scotland was encouraged by the Scottish exchange student her mother used to always have visiting at their home as she was growing up, so much that they kind of grew up together. She calls Hope Vere her adopted brother. He never had sisters so to him, she is his sister. She has always figured that she had Scottish ancestry, so when her uncle did some genealogy research and found out that we do have Scottish ancestry, she wasn’t surprised. Now her fondest dream is to visit Scotland and share her love of Scottish heritage.

Jonathan Irvin – Chief of Athletics – Jonathan has been the festival chairman and heavy athletic director for the Iron Thistle Scottish Heritage Festival and Highland Games since its inception over ten years ago, as well as a trustee for USCO. He does a fantastic job of facilitating ideas & keeping us focused on moving forward.

Stephen McCauley – Chief Clan Officer -Stephen is Clan Johnstone, Murray, Scott and MacGregor. The McCauley name is of Scottish origin but was given to his family by a Indian agent in the late 1800’s. He recently visited his homeland of Dumfries and Galloway. His wife found his 3 times great grandmother’s tombstone in Lochmaben, a very moving moment of their trip. He actually loves haggis, not on a dare.

Stephen is a historian, including his Native American heritage and holds a degree in General Science. He is a carpenter, husband, and father of five.

Samonia CLM ByfordHistorian – Samonia is a ninth generation Oklahoman, and active member of Clan Grant (centered now in Duthil, near Grantown-on-Spey and Cairngorms National Park). She is also active in the Siol Lewis Sept Assocation for descendants of Ludovik Grant (Jacobite who was transported to the Colonies in 1716) and his Cherokee wife. Samonia, her husband Dennis, and their twins live near the Oklahoma State Capitol, and she serves on other boards and committees while marketing and distributing books in Cherokee. Craig Elachie!

Nicole RodriguezLinguist – Nicole has always loved bagpipe music and men in kilts. It was her guilty pleasure until one day a friend invited her to Scotfest in Tulsa. She stopped at the USCO tent, learned how to join and started coming to the meetings. When she realized the people she met didn’t think she was strange and were often more than a little bit of the same kind of strange, she kept coming. Since Nicole was quite the polyglot (someone who speaks several languages), Jonathan suggested that she learn the Lord’s Prayer in Gaidhlig (Scottish Gaelic) to recite at the Iron Thistle. That went so well that it turned into heading up a whole study group dedicated to increasing the use of Gaidhlig and continuing to expand her knowledge.

Jeremy IrvinTrustee – is a heavy athlete and one of our go-to guys for anything that needs to be done at the Iron Thistle.  It’s hard work being Jonathan’s brother (and being mistaken for Jonathan quite often), but someone’s gotta do it.

Tracy Sinclair Trustee – Tracy “accidentally” married Paul Sinclair before she really understood what she was getting into with this Scottish business, but now she’s an invaluable asset to USCO, the Iron Thistle, and Scotfest. Paul may be the piping director for the Iron Thistle and Scotfest, but we know who the real boss is!

Heather RobertsonTrustee – Heather has always had an appreciation of men in kilts & then I married one! She is the wife of Jack Robertson for 24 years & a mom of 3 grown kids. She always thought she was just German & Irish but it turns out she is also a Scot (much to her husband’s relief). She is a photographer, animal lover, and mother of chickens. She love building & refinishing furniture…sawdust is Heather’s glitter!

She has a strange fascination with T-rex & has been known to show up in costume…kilted. Yes, she’s a little weird but she fits right in with this awesome bunch!

Tim RobertsonTrustee – Like his older brother Jack, Tim has always loved his Scottish heritage. He is a proud and active member of Clan Donnachaidh. Tim firmly believes in the mission of sharing Scottish heritage, history and culture with his fellow Oklahomans. He has spent many years volunteering for and attending many events of USCO and decided that the time was right to join the team.
