Safety & Affiliations

Safety is at the heart of every service we provide for our clients.

We recognize the importance of complete safety training to emphasize the prevention of accidents. Our company conducts quarterly safety meetings/training sessions to emphasize to our (new & experienced) workers that SAFETY is our number one priority. We also have a program of biweekly paycheck stuffers, employee memos and monthly equipment safety checks. Additionally, many of our employees have been trained in basic first aid and are certified in CPR.
