Bill and Joanne have been in the mortgage industry, serving their clients, for well in excess of a quarter of a century.  They have combined to fund in excess of 3.5 billion dollars in mortgage volume.  They are a husband and wife team and specialize in residential, commercial and private mortgage funding transactions.

Both are avid golfers and spend their time either working or on the golf course.  They enjoy travelling to the Masters Golf Tournament in Augusta Georgia every year and have two cats named Augusta and Georgia.

Bill is a graduate of the Ottawa University Administration Department. He is a member of Mensa and past President of the Kiwanis Club of Ottawa as well as a past Lt. Governor of Kiwanis Division 12.  He enjoys golf, travel and work, especially arranging mortgages on the more difficult transactions.

Joanne is a member of the Mazerolle family of New Brunswick. She enjoys gardening, reading, travel, golf and animals.

They have founded the Mazerolle-Gosewitz-Wood Scholarship at the University of Ottawa and Bill helped found the Kiwanis Club of Ottawa Medical Foundation and Dr. Kanta Marwah Scholarship in Medical Physics at Carleton University.  They firmly believe – “giving in its purest sense expects nothing in return.”

Their business philosophy is “ we put ourselves in our clients’ shoes as if we were borrowing the money and then decide what is the best possible mortgage options.”  We rely on referrals from our past clients – therefore their satisfaction is our main objective.

Kind words from Bill and Joanne's clients:

Bill and Joanne secured an amazing mortgage for me in a very short period of time. They did the research, provided advice and made what is normally a stressful process simple and easy. They negotiated excellent terms and I could not be happier - their professionalism and patience (with my numerous questions) shone through and, as such, I do not hesitate in recommending Ottawa-Carleton Mortgage Inc. to anyone looking for a great team who will work in the best interests of their clients (and, speaking of interest, they found me a great rate!).

-- Lise

We chose Bill to help us get our mortgage because of who Bill is. His expertise in the mortgage market surpasses any other company. We are more than pleased with our new home. Thanks Bill!

-- D.A.S. Avila & W. Hoare

Bill & Joanne worked to secure my mortgage within an impossible timeline; drove documents to my office for signature; made every effort possible to insure I understood the process; worked closely with the other players to ensure a seamless experience; outstanding service, quality service, would highly recommend.

-- L. BouskillThe mortgage maze can be time consuming and difficult to navigate. Bill and Ottawa-Carleton Mortgage have always made it easy and effortless. I truly appreciate the thoroughness and the speed with which Bill moves the process along. Bill has helped me with a number of mortgages and I have referred a number of friends and acquaintances to him. We enjoy the experience and the great customer service that is consistently provided to us. -- T. Kyle

I wish to make you cognizant of my family's experience. Our mortgage was up for renewal this past summer, and we had never thoroughly enjoyed past dealings with banks, (in general). We had often experienced feelings that seemed disingenuous. We often felt that our needs came second to the bank's wellbeing. We rarely got their best rates up front, and often needed to haggle.

This time we decided to try something different, and explore the "mortgage brokers". We dealt with Joanne Mazerolle-Gosewitz, from Ottawa-Carleton Mortgage.

My wife and I truly appreciated her expertise, professionalism and dedication. She always replied to our questions and concerns. Joanne was able to alleviate the stress often associated with mortgages, signing documents, legal issues, commitments, etc. Even their offices are more refreshing and less intimidating than the banks.

-- The Farley Family

This was our fourth time dealing with Ottawa-Carleton Mortgage. As always they handled our new purchase with professionalism and tack. This allowed for on-time service, resulting in complete satisfaction on our part. Great work Joanne.

-- P. &. S. Miner

Our recent purchase was the 2nd time we utilized the service of both Bill & Joanne Gosewitz. It is without hesitation that we can say, "they take the hassle out of mortgage hunting"!

Bill is personable, professional, polite and most importantly, just a real nice guy who makes you feel comfortable. I would recommend anyone to render Bill's service

-- T. J. Torosian

Joanne has a warm friendly personal style that would put anyone at ease. The service I received exceeded my expectations and was quick and effortless on my part. Even my lawyer commented that I got a great rate. Actually he said a "great mortgage"! Highly recommended!

-- L. McCarthy
