SDMG needs your help! We are doing everything ourselves, so we need Volunteers to help out. If you have construction or plumbing skills or energy for cleaning, repairing holes in walls or ceilings, degreasing oil from walls, painting, please consider lending a hand. If you can contribute painting supplies or lend tall ladders for the project, we could use them. Please contact Mark Herman. Thanks for everything you can do to help us improve the SDMG workshops for everyone’s benefit.
