The About page is one of the MOST looked at pages on a website. People do business with people, not with businesses. What's interesting about an About page is that you only want to include information about yourself that will be helpful to your client. You don't need to include everything about you. Start with what is most relevant and current. Don't start by telling people where you grew up and went to school. Tell them how what you are doing right now will help them.
In doing some research for an attorney, I found some examples of About pages I really like (I didn't create these websites):
https://www.perezcriminallaw.com/Attorney/ (Notice how he begins by letting the reader know that he understands what they are going through, then he tells them how he has the experience to help.)
https://www.poblenzlaw.com/About/ (Here's another one where she tries to show the client that she understands. I'd change this from third person to first person though. "I understand that you might be embarrassed by the charges against you or you might not even know you have certain rights under the law. My name is Michelle Poblenz. I am approachable, down-to-earth, and care deeply about my clients.")
As a contrast, look at this About page and see how much harder it is to relate to him:
A copywriter I follow has a great video about writing an About page. Take a look:
