I hope we get some responses to your question Lynn, not just to help you but because I think this will be very valuable information for other emergency managers to have. I sent a Tweet looking for information and will continue to promote this blog. 

Unfortunately my personal experience is using agencies, to fill positions not to find work, has not been good. After providing the agencies with a criteria which candidates had to meet, they persisted in presenting me with candidates which clearly did not meet the criteria.  I concluded that since agency management could not hire competent employees themselves, they clearly would not be able to meet their client's expectations. 

Just a further thought on Lyn's question. If we can get enough folks in the emergency management field using this blog there should not be any need to use, or incur the cost of using an agency.  

Please put the word out through your regular and social media communication channels to see if we can get more employment opportunities and  jobs wanted here. 

I have not used any recruiting agencies other than sending postings to Universities and Colleges and professional association websites/email blasts. 

I have had good success in recruiting students and graduates for field placements and summer paid positions using these methods.  Both education institutions and professional associations forward the postings on to their students and members and I have a good sized pool of candidates from which to draw upon.  This method also ensures that qualified people are applying for the positions.
