Diane Collier

As a full-time Realtor, I am a people person who enjoys a challenge. Transitions in life aren’t always easy. It is nice to have someone on your side who genuinely cares and looks out for our best interest and is willing to go the extra mile while keeping all lines of communication open. Personally, I have moved several times and know the stress related to real estate transactions; both being a buyer and/or seller.  My job is to help eliminate as much of that stress as possible during your positive real estate experience.

Please don’t hesitate to contact me on at 717-303-8990 or Diane.Collier@Century21.com



"Diane was a wonderful broker to work with and she went well beyond any expectations I had. She is very caring and fully accommodated my special needs. I would choose Diane again and recommend her without any reservations (and I have already done so. I was fully confident in Diane's abilities in advertising my property. What she chose to do brought quick results, for which I was very grateful. I don't think anyone could have done more. Diane is an excellent agent and a joy to work with. Century 21 is an excellent Realty Service and highly recommended. I am happy to share my experience anytime I can. My overall experience was totally satisfactory and the entire process was excellent. Because of my disability, Diane brought all paperwork to me, including the closing process. She made sure all my needs were met while I was in the moving process and showed personal concerns many times. I can't thank her enough for all her help." - Carolyn M. | November 2016


“Diane Collier is polite, respectful and very focused on the services she provides for her clients and she strives at providing the best quality of service possible, by listening to their ALL their wants and needs. She provides quick turn around with information and does everything within her means to work around the clients schedule and timing in acquiring signed documents, etc. More important than anything, was that she would call every once in awhile just to touch base with us and see if there was anything she could assist us with. We have purchased and sold several homes in the last 30 years and have never experience this type of awesome and stress free service till now. I fully recommend Century21 and Diane Colliers service, because they truly work FOR their client and with their clients best interests in mind.” – Chuck & Cathy H. | October 2016

“Knowing Diane from a common social organization we knew she was the kind of agent we wanted and needed and she met all our expectations, and treated us wonderfully. She was very aware of our stress factors and abated them very well. All characteristic were impeccable. Diane found us the right place for us, better than any others we'd seen and she guided us to the losing of the sale promptly and with great compassion.” – Andy & Ann W. | August 2016


“Diane kept me well informed with updates of what was going on from start to finish. We bought the house we now live in from Diane while selling the one we sold and I believe if it wasn't for her finding this house for us, we never would have gotten it and it was an awesome price for an awesome house and we love it!”– Joyce S.| June 2016

“Diane has been constantly considerate of my emotions as I sell my much larger home of 27 years and as I purchase a new much smaller home to accomodate my physical needs now. She's included my daughters in all decision making at my request and has also treated them with great respect. We couldn't have asked for a better agent to take care of us during this really emotional time in my life.” – Shirley A. | December 2015


“Diane is awesome to work with. She is patient and understanding and goes above and beyond for no matter what you need. If she can do it for your or help you in any way she will. I highly recommend Diane whether your buying or selling.” – Randy F. | December 2015


“Diane was more than helpful, l answered all our questions, always got right back to us when we called her, kept us updated in the progress of the property, I remember one evening it was snowing very hard & I thought dangerous to drive I told her over the phone to wait until the next day, but, there was Diane at our door giving us some documents. That is what I call dedication.”  – Wayne and Vivian M. | April 2015


“Diane is extremely professional and yet very friendly. She was driven to provide us with the best and stress free service that is humanly possible. She was very efficient in returning our calls and answering questions. if she didn't know an answer, she would say she didn't and then acquire the answer or provider us with a contact who could provide all of us (including herself) the answer. We will utilize her services in the near future to market and sell our current home after our dream home has been built on the land she just helped us acquire.” – Chuck and Cathy H. | April 2015


“Diane Collier was absolutely wonderful. Her knowledge, advice, compassion and availability made the process go smoothly on the sell of my house. Even with the small bumps in the road she was on top of it. If there ever is an occasion to recommend a real estate agent to anyone it would be Diane Collier.” – Pat G. | March 2015
