About Mary

Mary O’Neil considers it an honor to be involved in the purchasing and selling of homes. Her bachelors’ degree in social work helps her daily to help you! People tell her she is a great listener which is why she can work hard to get you what you want— not what she thinks you need.

She has been a full-time realtor since 1983 and is available 24 hours a day, 7 days a week. Furthermore, education is very important to her, and she has worked hard to earn the advance designations of Associate broker, C.R.S. - Certified Residential Specialist, G.R.I. - Graduate of the Realtor Institute, and P.I.C. – Professional Image Consultant (staging).

Mary is proud to consistently have been in the top 3% of the Downriver Association of Realtors. She has lived in the Downriver area almost 40 years. Her husband Bill and her have raised their three children there. They have a true appreciation of the small-town appeal that makes it such a great place to live.
Her hobbies include reading, cards, boating, and volunteering for church and community work. She also sits on the Grievance Committee of the Downriver Association of Realtors, along with the Allen Park Planning and Zoning Commission (proudly the first and only female member)! Mary is also a member of the Allen Park Tax Board of Review.

She hopes when you meet, you will see that Real Estate is her passion, not just her job.
