Joseph Lang, Raul Mendoza, Robert Lopez, and Colin Sattler are our Full-Time Home Inspectors


Joseph Lang - Owner
I grew up and was raised in Rancho Cucamonga. I graduated from Alta Loma High School and received my Bachelor of Arts degree from Cal Poly Pomona. Our family currently resides in nearby Upland.
I was granted the local home inspection franchise from Pillar To Post® in 2004. I have personally completed over 4,300 home inspections. I now concentrate on running the overall business operations, marketing, training our employees (including continuing education), and planning for continual expansion to provide a greater number of buyers with an exceptional experience. I have completed numerous home improvement projects in my personal residences and those of friends, so I have hands-on experience with plumbing, electrical and other household systems. I am a certified member of the American Society of Home Inspectors (ASHI®), which is their highest level of membership.
I have been married for over 20-years and have 4-children, all teenagers or older. Since I value family, I incorporate that into my business by the way I treat our employees and our clients. That way our inspectors are happy and they provide the best customer service possible.

Raul Mendoza - Home Inspector
I joined The Lang Team of Pillar To Post in 2015. I have been performing home inspections full-time since then and have completed over 2,000 home inspections. I have over 20 years of experience in the customer service industry and grew up the son of a handyman (my father’s profession until he retired). This background has been very beneficial as I help The Lang Team provide superior customer service. I am also bilingual in both English and Spanish and am excited to serve the Spanish speaking community.
My wife and I have 3 sons and I am blessed with my family. I look forward to serving other families as they trust me with their home inspection.
I view the job of a home inspector as being very technical as I look through the components of the home but also very customer service oriented as I guide my clients through the report and answer their questions.

Robert Lopez - Home Inspector
I joined The Lang Team of Pillar To Post in 2018. Previously I have worked as a termite inspector and repair for over 12-years, HVAC sales for 2-years, and solar sales This background has prepared me to become a great home inspector for The Lang Team. I have been performing home inspections full-time since then and have completed over 1,500 home inspections. I am also bilingual in both English and Spanish and am excited to serve the Spanish speaking community.
My wife and I have 3-children and we love our family. I love interacting with clients and guiding them through the home inspection process. I believe in performing the best inspection every time! This is not just a job, but a service I can provide to better the community.
