Mary Arnerich & Peggy Whalen

Complete Trust

Complete Trust I've worked with Mary (and Peggy!) now on two transactions, a buy and then a sell, each when I was out of state and the second during the pandemic. I felt completely at ease, knowing that Mary would take care of all the details and keep me constantly informed. Not only did my transactions go smoothly, but I sold my property (in part due to Mary's guidance on staging and painting) in about 48 hours for well over the asking price. I can't recommend Mary enough as a top-notch professional and trusted partner. She's the best!

Alton & Charmaine

We’ve bought a couple of homes over the years, and I must admit that dealing with them made the process much more manageable (and possibly even fun). What is normally a very draining process is balanced out by her contagious energy. She was very understanding and attentive to our needs. No matter how many times you go through this process, you'll always end up with a few challenges where questions may arise, and Mary made sure to get answers for all of them. In our unique case, we had a very tight timeline as we wanted to close on a location very shortly before we went on vacation, and Mary made what normally scared off most other Realtors to be possible. If you want someone to walk you through the whole process and will make sure all your needs are met, look no further. Or if you do decide to look further, only look a little bit further to her equally impressive partner...but then stop looking further after that.


Peggy is by far the most outstanding, hardworking, real estate professionals I have encountered, and I would not hesitate to hire her again or refer her to a friend. I knew she had the right expertise and tenacity, but I really came to appreciate her transaction management skills and just how savvy she is when it comes to selling a high-end home. Being a distance away, I relied on her heavily and appreciated every communication and the results of her hard work.

Kevin and Kimberly

As a master of contract negotiations, she came up with the deal that was good for us and was not afraid to push back on the little (but important) things. Since our purchase, she has also helped us sell a rental. You could not find a more attentive and knowledgeable agent. Our relationship was so positive, we have become good friends. We are pleased to recommend Peggy to anyone looking to buy or sell a home. She is hands down the best in the business in our opinion.


I remember meeting Peggy years ago and was impressed by her professionalism. Every phone call was returned immediately, every question answered correctly, and once I found the right home, the entire process was simple. and smooth. She continues to be a down to earth friend and business consultant to me.

Michael & Michelle

Mary helped my family and I manage a transition from Dubai, United Arab Emirates to Dublin, California. While it was a challenge to move internationally with two small children, Mary found a way to work on a schedule that fit my family's needs, provide my wife and me a holistic view of the options that met our decision criteria, and accommodate the challenge of a housing search with a 7 year old and a 2 year old along for the ride. She proved responsive, Insightful and Informed. Great people to lean on in our move who brought our family to our forever home.


Purchasing a home with Mary was both a professional and lucrative experience. In a hot Pleasanton market, I found a home and Mary's service was so swift and organized that I bought the house under asking price! The property needed a lot of updating, which definitely helped our negotiations. at the beginning of our home search, I knew that my criteria were challenging. Yet Mary's dedication and energy level never waned. She is amazing! I don't need another realtor in my address book - just "see Mary"!

Gary and Debi

We are so happy and grateful to Peggy Whalen for finding us our dream home – never thought it possible that the process could go so smoothly. We highly recommend Peggy for anyone looking to take the stress out of buying a home! It was a wonderful experience working with her and will continue to seek her guidance and knowledge in our real estate endeavors. We freely will be steering family and friends her way in the future.

Terri & Joel

Extremely courteous and really listened to our needs in preparing, listing, selling an closing our home. Mary was always very quick to respond to our questions and requests. If Mary didn't immediately have the answer to a question, she was able to quickly and accurately get a response back to us. I highly recommend Mary and have already given her a referral to a friend of mine looking to buy a home!


I cannot thank you enough for all your hard work, honesty and thoughtful communication when I was selling my parents home. I had never handled selling a home as a trustee and you calmed my fears and made the whole experience fun, easy and successful. You went above and beyond for me, and I know that I won't hesitate to recommend you to all my friends and family that are thinking of selling or buying.
