What do Clients Say?

We were very pleased with our experience of working with Pete as our realtor. He is a very knowledgeable, hard-working agent who is truly committed to representing the best interests of his clients. He patiently worked with us over an extended period of time until we found the perfect home for us and expertly guided us through the process! He also provided us with useful information about renting out our previous home. We would whole-heartedly recommend Pete to anyone looking to buy or sell a home and would definitely return to him if we were in the market again.

Scott and Sandra Seitz

Pete was instrumental in the selling of our home & the purchase of our new construction home. He is a true expert in the field!! He was patient & always available to answer questions. He worked diligently to sell our home. It is without hesitation, that we highly recommend Pete O'Connor!!

Jason and Karen Robinson

I had the pleasure of working with Pete O'Connor when selling my home and buying a new one. Through the entire process Pete showed passion, knowledge, attention to detail, and commitment. He was punctual and fast returning calls, texts, and emails. There was never a question without an answer and he took care of every single detail making it stress-free! I could not be more pleased. I highly recommend Pete to anyone looking to sell or buy a home. I look forward to the opportunity to work with Pete again!

Pete honestly needs more than 5 stars on every one of the categories listed above. As I see some of my friends, family, and co-workers start buying and selling their homes, I look back to how Pete handled our purchase(s) and sales. It feels like every single one has been a shorter duration from inquiry to completion, and we haven't had some of the same issues as other realtors (availability, knowledge, negotiation). Pete's top strengths are in local knowledge and negotiation. He provided us a hard data showing information on comparable homes in the market from recently solds, newly listed, and gave us reasons to why other homes were above or below value on our home.

About Stephen

After serving his country for 30 years in the United States Navy, Pete began his highly successful real estate career in 2005 with Shorewest, Realtors® until January 10, 2012 when, (after founding Power, Realtors®) he launched his first real estate Brokerage firm. During his tenure as President and CEO of that company, under Pete’s guidance and leadership, he was solely responsible for taking a start up company from nowhere to the number two real estate firm in its third and fourth years of existence, as well as his firm being selected as “Best of Kenosha” for five consecutive years. He was also solely responsible for his company gaining membership into the Leading Real Estate Companies of the world (Leading RE). After a number of unsolicited offers to sell, Pete sold his company in February 2016 and began laying the groundwork for Mastermind, REALTORS®.

Continuing on with his many successes, Mastermind, REALTORS® was founded on June 1, 2016 and launched on December 24, 2016.   Mastermind, REALTORS® has had the pleasure and privilege of representing a number of luxury home Clients as both Sellers and Buyers and we excel in this area. 


Pete has had the privilege of working with many high net worth individuals, some of them coming from old money and many of them coming from new money, meaning that Pete has represented clients who have brought their family and business fortunes forward over many generations and also those self-made first time millionaires making their leap into the luxury arena. Confidentiality and Service are just some of Pete’s trademarks.


As of December 31, 2020, Mastermind, REALTORS® proudly ranks in the top one percent of all real estate brokerage firms in the Southshore Realtors Association.
