Accessibility Adjustments

Accessibility Commitment for Peak Wellness

At Peak Wellness, we are committed to making our digital presence as accessible and inclusive as reasonably possible for all users, including individuals with disabilities. Our goal is to improve the usability of greenwich.peakwellness.com and to support a more accessible experience for everyone, regardless of their abilities or the technologies they use.

Our Approach to Accessibility

We aim to align with the Web Content Accessibility Guidelines (WCAG), which define internationally recognized standards for digital accessibility. While full compliance cannot always be guaranteed, we strive to implement improvements where feasible and regularly review accessibility-related aspects of our website. Accessibility is an ongoing process, and we are committed to improving the experience over time as technologies, standards, and user needs evolve.

Accessibility Features

To support accessibility, greenwich.peakwellness.com may utilize tools such as the OneTap accessibility toolbar. This interface provides users with a range of helpful features, including:

Adjustable text size and contrast settings
Highlighting of links and text for better visibility
Full keyboard navigation of the toolbar interface
Quick launch via keyboard shortcut: Alt + . (Windows) or ⌘ + . (Mac)

Please note the following:

The availability and effectiveness of these features depend on the website's configuration and ongoing maintenance.
While we strive to ensure accessibility, we cannot guarantee that every part of greenwich.peakwellness.com will be fully accessible at all times. Some content may be provided by third parties or affected by technical constraints beyond our immediate control.
