“Jim and Sarah work with us to find deals that we can acquire and they are very good at it! They are certainly always responsive, they know the business extremely well, and most importantly are fun to work with.”

Jason Costello, Cabrio Properties

“Upon a “second” building recommendation from John Porth, we have found a building for EDSS and are very happy. John is a detailed professional, easy to work with and has been available at any given time to accommodate our schedule to look at buildings. John worked with us on exactly what we wanted and found the right fit for EDSS. Five years ago, John found us our current building and now this year, we have a new home. We thank him for his expertise and dedication to EDSS, his client.”

Sonja Berry, Chief Operating Officer (COO) Energy Design Service Systems (EDSS)

“A friend suggested that I use Jim Porth if I wanted to sell my 3 properties in Ann Arbor quickly, and that he did!  One weekend after listing the properties, we had an offer and signed the deal. There were a number of issues with financing on the buyer’s side but between Jim and Sarah, all things worked out to our satisfaction and we closed last week! It took less than 90 days…That’s pretty nice! “

David MacKool, former Ann Arbor property owner

“Jim has really been terrific to work with. He has come through for us in tough situations and he helped affect a positive outcome on numerous occasions.  I highly recommend Jim and his team to anyone.”

John Langs, Magellan Properties

“We were satisfied with the services you provided and would recommend you to a friend.  You kept us up to date on the showings and the status of the deal and your willingness to kick in a point on the commission to get the deal done was key to us agreeing to the deal.”

Tom Munley

“Jim goes above and beyond for his clients. He is smart, straight up, and sincere. I would highly recommend Jim, and will most definitely use him in the future.”

Heather Dupuis, Co-Owner of Vie: Fitness & Spa

“It has been a real pleasure working with Jim. My partner and I recently developed one of the largest projects in Ann Arbor to happen in years (Arbor Hills). We opened over 95% leased in part due to the hard work of Jim. We currently have other sites tied up, Jim has been, and will continue to be heavily involved. I cannot say enough about Jim’s tenacity and professionalism. I also cannot imagine working with anyone else in the market.”

Max Reiswerg, Owner of The North Shore Properties Group

“If you want to buy or sell any commercial property, you should reach out to a team that will get the job done. Sarah and Jim are hardest working realtors that I know. They got me the best offers for the properties I sold, and they will find me the properties that I am looking for at the right price. I strongly recommend them without any hesitations.”

Dr. AJ Farha

“In my experience in working with Jim, he has been consistent in his level of professionalism, honesty and integrity. He is always responsive and fair in his real estate dealings, always putting his clients #1.”

Joe Schimizzi, Acquira Realty Holdings

“Two years ago I negotiated a lease using an attorney and dealing with the landlord for the bulk of the negotiations and it was so stressful. This year, I had Jim Porth negotiate two leases for me and it was a breeze. I could do this all day if Jim handled it for me and it would actually be fun. His many years of experience and creativity were fantastic. I highly recommend him! Can’t wait for the next one!.”

Dr. Nicole Teifer, Orthodontist and Founder of Today’s Orthodontics + Pediatric Dentistry at Canton and Novi

“I have had numerous real estate transactions in the past ten years, both as a buyer and as a seller.  Jim and Sarah have worked closely with me on all of them ,  developing creative solutions to some very challenging situations. They have always come through. I highly recommend them.”

Sam Falk, Allstar Wireless

“Sarah and Jim gave me excellent customer service with a high degree of professionalism, and followed up on all my matters for property settlement.  They worked with my bank closely to get my property financed.  I highly recommend them.”

Dr. Mohammed Arsiwala, Michigan Urgent Care

“It is a pleasure working with Jim.  I have always found him to be candid and forthright in his practice of real estate…”

Larry Zahn, RE/MAX Commercial Brokers

“Jim and Sarah were a pleasure to work with. They were very diligent in their search, but also very patient with me. I look forward to a continued relationship and working with them again.”


“I was extremely impressed with the service I received from Jim and Sarah. I have been involved in real estate for over thirty years and would rate them in the top 10% of all the agents I have worked with. They got me the price that I wanted, effectively worked through the inevitable issues that arise on the way to a closing and were a pleasure to work with. I highly recommend them.”

Larry Nisson

“Selling a building is not an easy task. John and Jim Porth were so helpful and wonderful to work with. They handled everything. I was able to focus on running my personal business and not the building so I could continue doing what I do best and clearly let them do what they do best. The sale was a success. A world of thanks to them both!”

Kathy Nohr, Nohr & Associates
