Certifications and Partnerships

I have been working with A-1 Personnel for the past 3 years and I am very pleased with the quality of service they have provided. Harris Country Sheriff’s Office needs have been specific with a very tight pay margin and timeframe, A-1 Personnel has worked very diligently on these: they are always quick in response, extremely friendly and knowledgeable and were able to supply the quality candidates for us. I Strongly recommend A-1 Personnel of Houston as staffing providers due to our great experience with them. 

A-Personnel is always very responsive to City of Houston’s needs. Their staff inquires about what skill sets we are looking for and sends us qualified applicants. They are also very prompt to provide us with applicant’s resumes and schedule interviews. We have used their services several times for temporary assignments throughout our agency.  I would highly recommend A-1 Personnel to others because of our satisfaction with their service.
