I confidently recommend Joshua Nash and his company Kingdom Cleaning for office cleaning services.  Mr. Nash has worked for SWCA Environmental Consultants as our cleaning person for ten years.  Our office consists of two buildings and approximately 5,000 square feet.  During his time working for us, I have found Mr. Nash to be extremely trustworthy, loyal, consistent, committed to timely and clear communication, on-time, on-budget, and to have excellent cleaning standards.

Additionally, on a number of occasions Mr. Nash has brought to my attention items outside of his purview needing to be repaired, and/or weekend/nighttime activities around the office.  I really appreciate

Here is my “Top 10” for Kingdom Cleaning!


1. Professional — Josh knows his field, and his work and presentation are excellent.

2. Reliable — We have never had a situation where the work was not completed as agreed.  I’ve spent time in the past wondering if the work would be done, and I have no concerns about that now.

3. Joyful — Josh is friendly, interacts well with anyone he meets on the job, and exudes delight in meeting our cleaning needs.  It’s not just a job.  He does it passionately and happily.  Our success is his success, and he is genuine about that.

4. Serving — There is never a doubt that Josh desires to meet our needs with excellence.  He willingly considers adjustments that serve our needs and allow us to fulfill our mission.  He is attentive to making sure our buildings sparkle and we present a pleasing environment.

5. Approachable — Any time we need to talk about anything, Josh is open, receptive, and takes the necessary time to ensure his service meets our needs.

6. Effective — He does what he says.

7. Thorough — He meets and exceeds expectations.  He knows what needs to be done and gets it done.

8. Integrous — There is no hint of shadiness or cutting corners.  He keeps his commitments.  If needed, he brings things to our attention.  A companion term would be trustworthy.

9. Complaint-free — I’ve learned over the years that those who provide cleaning services get too few compliments.  You know they are doing their job when no one complains.  And for me, it’s a great relief and security that no one complains about the cleanliness of our buildings.

10. Reasonable — Josh provides exceptional work at a fair price.


If you don’t have my drift yet, we are a very satisfied client and delighted to have Kingdom Cleaning provide this service.

Joshua and his company, Kingdom Cleaning, are dependable, reliable, always on time, and they keep our office clean beyond normal standards.  They clean our building like nobody has been there, and that’s what you want, right?  I also feel that they are very trustworthy.

Family-owned Villa Automotive has taken care of San Luis Obispo's automotive repair needs for over seventy years.

To whom it does concern: I am John Villa, the CEO of Villa Automotive.  We have been in business and serving San Luis Obispo since the turn of the century — fourth or fifth generation business.  We like doing business with family-owned businesses because we are a family-owned business, and because they care and they make sure things get done right.  If things don’t get done right, then you have full access to the boss who will make sure things get done right. Service is only as good as the service behind it.  My opinion is that Joshua Nash is a fantastic individual. I’ve been working with him for over a year, as his company cleans my headquarters on a weekly basis. When I had a few problems, he took care of

the problems.  That tells me that he is a good man.  Business is only as good as you care for people’s problems. Everybody is going to have a problem. How you take care of problems tells me what kind of businessperson you are. And he is the guy.  You are not going to have any problems with him!
