Why a joint venture?

The Americans with Disabilities Act is one of the most important pieces of civil rights legislation in the history of our country. Signed into law in 1990, it has quite literally touched all our lives by transforming the landscapes around us to create inclusive spaces inside and outside. This is all for the good and deserves to be celebrated. However, the work is far from over. Employment of people with disabilities has not undergone the same radical shifts that we’ve seen in the physical spaces around us. As we move deeper into an information-driven world, this pre-internet legislation has not adequately dealt with the obstacles for those living with use constraints – no matter if they are applicants applying online, employees using inaccessible tools and software or consumers trying to connect to important information.

This joint venture was born from the understanding that dealing with only one area of a business or one department is not going to adequately accelerate the change that we all need now. Together, The Sierra Group and Tamman can affect the multiple dependent departments at the same time. We are the one-stop shop for your Diversity, Equity & Inclusion, HR, Recruitment, Legal, Marketing, and Technology needs. No other venture offers this one of a kind 360-degree comprehensive approach for your team’s accessibility needs.

From technical demonstrations and assessments, to full-service consultation and remediation, our approach to inclusion will guide you and your team to meet the employment provision of the Americans with Disabilities Act, both as the law and the spirit of inclusivity for all employees.

It just makes great business sense to do the right thing.

Combining the Americans with Disabilities Act (ADA) and Web Content Accessibility Guidelines (WCAG), this joint venture can assess, train, remediate, recommend, and consult on the range of issues facing your businesses, returning the highest value to your stakeholders and customers.
