Everyone has their niche in the world where they find the most joy and fulfillment. For me that has become Accessibility. Some of my experience comes from my personal ordeals I have gone through as I have steadily learned more about what makes my brain tick and what makes my joints throw a temper tantrum. My professional experience has helped me along the way because it is where I learned just how diverse the options were for accommodations, treatment, and more.

I was initially thrown into the deep end during my amazing journey with the American Printing House for the Blind's Internal IT department. I gained insight to some of the struggles caused when environments, processes, technology, and attitudes are not accessible. However, I also experienced great joy every time I managed to help make someone's day easier by helping them be more independent and confident in themselves. Since then, I have held many other Accessibility related roles and made it my mission to spread Accessibility awareness. I've done so through by improving Code Louisville's Accessibility policies and coursework as a mentor, speaking at domestic & international events, providing support online, and so much more. I plan to continue to do what I can for as long as I am able.

For the past 15 years, I have been an integral part of many successful organizations due to my experience and dedication. My coaching and consulting has allowed clients to achieve excellence as well as exceed their goals. It has been a privilege to be associated with such great achievements.

My Human Centered based methods have been proven to be successful, having been applied in a variety of projects with resounding results. My approach is comprehensive, taking into consideration all contributing factors to obtain the desired outcomes for clients that provide real value.

I'm passionate about empowering individuals and systems to identify and tackle the obstacles they face on their journey to success. Building trust within their systems through means of inspection, experimentation, and adaption we revise collaboration, & communication. I'm committed to helping my clients achieve long-term results. My ultimate goal is to support them in C.E.C. so that they can make lasting progress in life.

Collaboration is critical for the success of any solution. Working with a diverse group of people helps produce more effective results, and that's why I always strive to create an atmosphere where such collaboration can take place. By leveraging the skillsets of different individuals, we can develop high-quality solutions in a timely manner.

Experimentation is an invaluable tool in finding suitable solutions. To approach a problem in an effective manner, it's important to look beyond the traditional methods and explore something new. This might include using different techniques or tools to test out potential ideas and uncover the best solution. Experimentation gives us a chance to discover and try something that could potentially be groundbreaking, so it shouldn't be overlooked when dealing with complex problems.

Trust is essential for any team or organization to be successful. This confidence is established through effective communication and how information is shared. It's important to understand the power of these interactions, as they can create a feeling of reliability that allows everyone in the group to collaborate confidently.

The challenge organization’s face today is how to sustainably provide for the needs of growth while simultaneously protecting what has been built. A balanced approach is needed, one that combines sustainability with modern innovations. We must build a foundation for future prosperity that takes into account the needs of the organization, individual and the consumer.
