Website Content Update Needed

I need assistance with updating specific content on my website. The tasks include removing certain credentials from a team member's name and adding both mailing and physical addresses to the 'Contact' section. Unfortunately, I'm unsure of the platform or technology used for the website, and I don't have confirmed access to the admin panel.

Key Requirements:
- Remove "MTA" from Peter Mutch's credentials under the 'Team' section.
- Add the following addresses to the 'Contact' section:

Mailing:
134 Kent Street,
Box 111
Charlottetown, PEI C1A 8R8

Physical Location:
125 Great George Street
Holman Office Building
Fourth floor, Suite 400
C1A 4K7

Ideal Skills and Experience:
- Experience with various website platforms (WordPress, Wix, HTML/CSS)
- Ability to navigate and edit website content without clear platform information
- Strong communication skills for updates via email

Please reach out if you can help with these updates, and provide guidance on accessing the necessary sections of the website.
