Custom column help- custom column based on multiple conditions

Hello All:

I am new to PowerBI but have some basic programming/SQL skills WAYY back in my career.  I am trying to make a custom column called QualityProject using PowerBI that will show either a "Yes" or "No".  Here's a representation of my table and the columns that would be involved:

Here's my psuedocode:

IF ProjectStartDate>=12/1/2019 AND ProjectStatus=Complete AND ProjectResults=Target OR Stretch AND CountofTOC>=1

THEN QualityProject = Yes 

ELSE QualityProject = No

I would then like to make a table visual with this that would show the Team Name and a count of the projects where QualityProject = Yes (a team could have multiple projects, some would have Yes in the QualityProject column and some would have No depending on the criteria of the project).  I have a Team table that is already related to the Project table in a one to many relationship.  

What would be the easiest way to go about all of this in PowerBI?  Thanks for any help/advice in advance!
