Jim Rivett Memorial Charity Golf Tournament

Umbra Group (Linear Motion, LLC – Thomson Aerospace & Defense) and the UAW Local 2275 are jointly hosting their annual charity golf outing on Saturday, July 22, 2023, at Twin Brooks Golf Course (NEW LOCATION), 1005 McKeighan Road, Chesaning, Michigan.  View flyer and registration form »

This event is celebrating its 34th year of the annual golf outing. Our goal is for continued growth to increase the charity contributions while offering a fun-filled outing for our employees and guests.

Jim Rivett, while employed in our Metallurgical Department, became afflicted with ALS. In addition to his battle with the disease, the 24-hour care medical costs weighed heavily on himself and his family. In July of 2001, our dear Jim lost his battle with ALS. Since then, we have been honoring him with this annual charity golf event and have arranged for all donations to be exclusively directed towards patient care.

Since ALS of Michigan became our charity of choice, a total of over $47,801.00 has been donated. The committee also elects a second charity and this year, in addition to ALS, we will be donating to the Valter Baldaccini Foundation.

We hope you will be able to join us. Pricing for a (4 person) team is $260 (or $65 per person).

We hope you can also support our cause by purchasing a hole sponsorship at a cost of $150.00. If you have the resources, businesses and individuals can also support this tournament by donating door prizes or funding for door prizes.

Registration will begin at 9:00 am with a shot gun start at 10:00 am.  A catered dinner will be served immediately following the tournament.
