Counting Clients On First Day Of Month Adhoc

I am trying to write a query that counts how many clients were part of program at the first of each month.To make it simple, the data comes out of one table which looks like this:

Client # Program Start_date End_date
1 Fruit eater 03-27-2014 01-10-2015
2 Veggi eater 01-16-2015 null
3 Veggi eater 12-05-2013 04-16-2015
4 Fruit eater 10-01-2014 11-30-2014

Currently I have a very ugly solution that I know is not the best one:

Select
sum(convert(int,Jan_2014))as Tiers_in_Jan_2014
, sum(convert(int,Feb_2014)) as Tiers_in_Feb_2014
, sum(convert(int,Mar_2014 )) as Tiers_in_Mar_2014
, sum(convert(int,Apr_2014 ))as Tiers_in_Apr_2014

[code]....

Is there a better way to write this query?
