To: Carson Taylor <ctay@beemail.com>From: Edward Ling <eling@lingspencerlaw.com> Subject: Re: Legal aide position Date: September 22Dear Ms. Taylor,Thank you for replying to our job posting for a legal aide published in the Hudson River Times. There has been a lot of interest in the position, but I have come up with a short list of candidates I would like to interview. I am pleased to inform you that your name was among those selected. — [1] —. I was very impressed with your references, particularly the one from attorney Helen Dawes. She explained that you were her legal aide for five years, and that although the small size of her firm required you to have many different responsibilities, you excelled in them.— [2]—.My firm is also modest in size with two attorneys. In addition, we also have two legal aides and a receptionist on staff. — [3] —. However, we have found that the caseloads my colleague Arnold Spencer and I have taken on are creating more work than our current staff can deal with. — [4]—.Mr. Spencer and I will be conducting interviews on September 26 and would like to meet with you at 10:30 a.m. at our office on 4464 Trevor Avenue. If that time doesn't work for you, please let me know when is best to meet and I will try to accommodate you.I hope to hear from you soon.Sincerely,Edward LingAttorney, Ling & Spencer Law Firm
