Adam Grate

Licensed Inspector

Adam joined Enlighten Home Inspections in 2017. Before moving to DC, Adam lived in St. Louis and was a general contractor for 5 years after being a carpenter for 10 years. Clients regularly let us know that they are impressed with Adam’s professionalism and attention to detail. He is patient and excellent at answering technical questions. When Adam is not performing inspections, he is likely working on gut renovating his own property. Adam has been an expert witness and has a vast knowledge of best building practices.

Zach Warren PhD

Licensed Inspector

Zach has a MDIV from Harvard and a Psychology PhD from Georgetown! Zach was a former client of Enlighten Home Inspections; we helped him inspect a 4-plex that he purchased. When Zach is not performing inspections, he is investing in and flipping houses in Baltimore. He has flipped over 10 properties to date and is currently working on several more. Zach has a strong passion for real estate, which is obvious when you talk to him. Zach has many amazing accomplishments, the most unbelievable may be that he once held the Guinness world record for joggling (he ran a sub 3 hour marathon while juggling)!
