Wiping the drive before doing simple troubleshooting is like amputating your foot because your toenails are too long. A wipe/reinstall should be looked at a last resort. Often I believe even Apple phone techs are too quick in suggesting that. Have you done other troubleshooting before posting?
If not, we may be able to find that it is something simpler, but we need more information first.
1) What MacBook Pro sub-model? For "About this Mac..." and what OS version is it running?
2) What symptoms are you experiencing? Are issues limited to certain programs? CAn they be traced to the recent installation of any system or security updates.
If the computer is running, you can save us playing "20 Questions" with you by posting a system config snapshot. Fortunately there is a safe, secure way to do that. We can quickly and within the confines of these forums help you determine if software issues are the problem if you use EtreCheck, available free from the Mac App Store here:

We can also see hard data about drive performance and RAM usage. Etrecheck is the development of a long-serving and trusted contributor here expressly for displaying information in these forums to help us help you. It will not reveal any personal or secure information.
Run it, select “Report" from the left-hand pane (scroll down to the bottom of that pane to find):
When its report displays, click the "Share Report" icon from EtreCheck’s toolbar and then "Copy report” from the resulting dropdown.
⚠️ Please DO NOT highlight the text in the report before using Etrecheck’s “Copy report” command—that will garble the formatting and make the report slower and harder to evaluate.
NOTE: Changes in late 2018 to the forum software require you use the “Additional Text" icon (see example below) to embed the report into a post:
Paste the report into the resulting “Additional Text” window:
