Dianna Mandzuk's Expertise

Dianna has knowledge of a wide geographical area which she acquired in her 35+ year real estate career stretching from urban to rural areas from Durham Region to Northumberland County, County of Peterborough with Cavan-Monaghan, Millbrook to the lower section of the City of Kawartha Lakes and all areas in between.

As a lifetime resident of the Regional Municipality of Durham, being one of Canada's fastest growing economic communities, and being made up of the Cities of Oshawa and Pickering, Towns of Ajax and Whitby, Municipality of Clarington and Townships of Brock, Scugog and Uxbridge are all areas that are well known to Dianna who as a child was raised in Courtice and now resides on the outskirts of North Oshawa in a rural setting for the past few decades.

With familly and friends residing in Northumberland County which takes in seven diverse, yet complimentary Municipalities and specifically the Township of Alnwick/Haldimand, Municipality of Brighton, Town of Cobourg, Township of Cramahe, Township of Hamilton, Municipality of Port Hope and Municipality of Trent Hills, these are also areas Dianna is very familiar with and has frequented over the years.

Owning several properties and enjoying a second residence on the shores of Pigeon Lake in Bobcaygeon, the City of Kawartha Lakes is the second largest single-tier Municipality in Ontario by land area with the main population centers being the communities of Lindsay, Bobcaygeon, Fenelon Falls, Omemee and Woodville which are all communities Dianna has enjoyed spending leisure time in with her family and friends.

Dianna is "low-key" and "no pressure" when it comes to real estate. Dianna's personable attitude and strong work ethic get the job done with the least amount of stress for her clients as possible. 

She is always available to you, 24 hours a day, 7 days a week; just a phone call or a click away.  The Team's admin staff can be reached week days from 9am to 5pm and will be able to assist you with any questions you may have or will be able to put you in touch with Dianna or any of the other Team members.  After hours, your call will be answered by a receptionist who will be able to page us your message.  We will return your call as soon as possible!

Dianna focuses a large amount of energy and dollars on advertising.  Your property will have exposure in the Homes and Land of Durham, a glossy magazine publication with a 1 month shelf-life with a wide distribution throughout the area.  We will produce full-colour feature sheets that will be left at your property for potential Buyers and Buyer's Agents to take with them after they have viewed your home.  These serve as a visual reminder to help Buyers remember your home and to make it stand out in their minds.  Your property will also be listed on our website 24/7;

There's a human element present in each and every real estate transaction - - it's not just contracts, negotiations, offers and counter-offers.  When you choose to work with Dianna Mandzuk and a Team member of the Dianna Mandzuk Team, you can be assured that we take the time to get to know your needs and wishes and will do all that we can to achieve a successful conclusion to your real estate transaction, whether it be buying or selling.
