ORDER BY DATE showing NULLS first then most recent dates

I have a stored procedure which executes a select statement. I would like my results ordered by a date field and display all records with NULL dates first and then the most recent dates.

The statement looks like this:

SELECT a,b,c,[Submission Date]
FROM someView
ORDER BY [Submission Date] ASC

Now this will display all records with NULL Submission Dates first, but when I get to rows that have date values in them, they are not the most recent dates in the view.

If I replace ASC with DESC, then I get the dates in the the order I want, but the NULL values are at the bottom of my result set.

Is there any way to structure my query so that I can display the null values at the top and then when there are date values, to order them descending most recent to oldest?
