Hillside’s Customer Service Team Earns A+ Rating from the Better Busines Bureau

Hillside’s BBB Accredited Business rating is an A+. 

BBB ratings represent the BBB’s opinion of how the business is likely to interact with its customers. The BBB rating is based on information BBB is able to obtain about the business, including complaints received from the public. BBB seeks and uses information directly from businesses and from public data sources.

BBB assigns ratings from A+ (highest) to F (lowest). In some cases, BBB will not rate the business (indicated by an NR, or “No Rating”) for reasons that include insufficient information about a business or ongoing review/update of the business’s file.

Torch Awards for Ethics

Hillside has been awarded The Torch Awards for Ethics.

The Torch Awards for Ethics honors companies whose leaders demonstrate a high level of personal character and ensure that the organization’s practices meet the highest standards of ethics, and consequently generate trust. These companies’ high level of trust is recognized among their employees, customers, and communities. The award embodies Better Business Bureau’s mission to be the leader in advancing marketplace trust.
