Greg Marell seemed very experienced, but he's not as thorough as I would have liked. There were a few recommendations he made that were completely contradicted by later experts we hired. He claimed there was an inaccessible area of crawl space that turned out to be slab, and he claimed the roof needed immediate replacement but multiple roofers disagreed. He also failed to check the functioning of at least our washer and dryer, which are both nonfunctional (and the dryer duct had detached from the wall, leaving an open hole!)
