We had a great experience selling our home with the Foss group. Dennie and Kate were superb and stress-free to work with as they guided us from listing all the way to closing. Pictures of the house were done promptly. Photographer was professional and Kate & Dennie helped with the staging. Offers came in a few days later and we went under contract in less than a week. All of our many questions were promptly answered; despite the compressed timeline we never felt pressured and had ample time to consider our options. Process to closing was the same way, we were kept informed and all of our concerns were promptly resolved. Dennie even helped us out with a couple of last minute moving related logistical issues. They truly are a dream team; I highly recommend Dennie and Kate if you’re looking for a top notch realtor team.

To whom it may concern:

Dennie and Kate Foss are a brother and sister realtor team. They came highly recommended to me for their knowledge about the community in which I hoped to settle. It is a team that works well together and compliments each other’s skills. They are successful in all the aspects of their Realty work from start to finish.

One of the many reasons that I recommend them is for their trustworthiness and sincerity. Dennie is an outgoing and enthusiastic realtor who is determined that the clients’ needs for the perfect home will be met. He makes himself always available to be helpful and follows up quickly on client questions by tirelessly searching for the answers.

Kate works diligently to match the homes selected for viewing to the client’s needs. She accomplishes this by truly listening to the client’s interests about the community as well as the individual home to be selected. Kate has a vast outreach among other realtors. She relates well to the client and willingly gives her opinion when asked.

This is the team that makes finding a home a joyful and fun occasion. They are both warm hearted keeping the client’s interests first and foremost.

Dear Kate and Dennie,


I can’t thank you enough for getting me into my first home.  I absolutely love it, and wouldn’t have gotten there without you.


I didn’t quite understand why I needed a team to help me sell my condo and find a house, but with all the things you do it really does take a team effort. 


The pictures you took of my place made it look amazing and surely helped sell it within days of listing it.  But that’s when the fun really began.  Having you guys be there for the home inspection was one thing, but to be there for the burner cleaner and the mold surveyor, and picking up and delivering my repaired screens was above and beyond – it felt like there was nothing you wouldn’t do to get me to the closing on time.


I thought I’d be homeless for a while because I just wasn’t seeing things in my price range, but you were great about exposing me to places I might not have considered otherwise, which helped me see what a great bargain my house was when I saw it.  Your guidance through the negotiations left me very satisfied that I got the best deal possible.


I just can’t say enough about what a pleasure it was to work with you guys, as it has always been.


Thank you again.  You can be sure I’ll be recommending you to anyone looking to buy or sell a home.

Jen was our rock. We have been looking for over a year and were starting to get a little anxious. Jen helped us stay positive, focused, and optimistic in a very crazy market. She was always available via text, phone, and to meet us at listings and open houses. Her expertise in the building/construction area was reassuring - we knew we could trust in Jen to point out any issues or concerns, or to reassure us as to what was normal or typical (and not to be concerned about).

- Angela S

It was a great experience working with Jennifer! As first time home buyers, she made the process an absolute delight! She was able to find us the perfect home, in the perfect location. She answered all our questions quickly and efficiently and was instrumental in getting us the property we got. I wouldn’t recommend any other agent!

- Jessica N

Kate and Jen are absolutely the best at what they do! There is no question in my mind that I wouldn't be in my first home today without their knowledge and expertise. They far exceeded my expectations by going above and beyond every step of the way. Granted, it was my first experience with a real estate agent...but they were always extremely responsive, made it stress-free, and showed lots of patience when things weren't always going perfect. I would recommend them to anyone buying or selling in a heartbeat.

- Raymond I

Communication and follow through on questions asked could have been better. Both realtors were friendly, sweet and professional . They are both laid back and chill. Our personality tends to be more fast paced and definitive . Our overall goal was accomplished and on our schedule, and they brought us through it. For this we are extremely grateful !

- Laurie B

I couldn’t be happier. It has been hard finding a house in this market. Jen was always honest with me to keep expectations realistic but we ended up finding my family’s forever home!!

- Danielle L

Thanks to Jennifer I am now the happy owner of a new home

- Eileen K

I knew Alston Foss and she partnered with Jennifer. Everything when smoothly from start to finish.

- Jennifer D

Jennifer Russell was a pleasure, and we are grateful that she helped us with the sale of our house. She was prompt and efficient, and she always led us in the right direction to make everything run quick and smooth. Thank you Jennifer, once again for the quick sale and your calming ways to get us to the goal!

- Mary T

Jen was very attentive to my needs and was always there when I had a question, even on weekends

- Kenneth K

We have used Jen Russell several times as she is always knowledgeable, responsive and personable.

- Karen R

I cannot begin to fully explain the worth of having Jen, not only as our seller's agent but as a person in general. She was a complete professional throughout the entire process and had an invaluable amount of knowledge in the new construction and condominium real estate industry that allowed the transaction to go through as smoothly as possible. I would recommend the Queen of Condos to anyone that is willing to listen!

- Lyndsie R

Jennifer is a pro. She has always gone the extra mile to assist and with her extensive experience, guides the deal to insure a smooth closing. I would highly recommend Jennifer for all your real estate needs!

- Paul R

Excellent agent, very knowledgeable and always timely. Great communication throughout the process.

- Sean C

We first met Jennifer when as a young woman she worked for her father, who built our condo and built (rough estimate) 500 to 1000 condos and homes in Newmarket and surrounding towns. There was never any doubt we would list with Jennifer, and when after 15 years we decided to move to a warmer climate we called Jen. She is amazing. There were times when she knew more about our condo than we knew! That is really helpful when you have to complete a seller's disclosure form. Whether it was needing an electrician for a minor repair or getting some paperwork from town hall, she is right on top of everything. Jen knows condos, she knows construction, she knows the local market. This was a stark contrast to our experience of buying a condo out of state, where both the seller's broker and the buyer's broker (i.e. our broker) were often clueless about the condo development and we as buyers ended up doing some of their work. A broker like Jennifer is a rare find.

- Kristen B

Very satisfied with Jennifer.

- Stephen T

I’ve used Jennifer in the past to sell and purchase a new home. When I decided to sell again, although the situation was difficult, she was professional and honest and extremely helpful in locating my new home. It was a difficult negotiation and she handled it with ease. She was fantastic getting my existing home under contract and her calm demeanor in purchasing my new one was amazing Thanks Jen!

- Karen G

When it came time to sell a house and find a new one, Jen was the obvious choice for me. Her hard work, integrity, and and knowledge were tremendous assets, and she made the process very easy to navigate. She was able to get answers even when the parties on the other side of the transaction were challenging to communicate with. I would recommend Jen's services to anyone looking to buy or sell, and especially when dealing with new construction.

- Steven M

Jen was just overall great to work with

- Leo D

Jennifer was very helpful with all the unexpected things that happen during the sale of a home. The amount of stress she relieves during this process is remarkable. I would highly recommend her to everyone I know looking for a realtor.

- Trustee S

Jen was absolutely amazing and we couldn't have done this without her. It was certainly a roller coaster ride selling our house and Jen really did a great job on keeping us calm and managing expectations. Jen's expertise really showed and she was able to sell our house within our tight timeline and got our asking price. We can't thank Jen enough, and we really appreciate the handwork she put into getting our house sold.

- Corey C

Working with Jen was great! People always told me that buying a house would be one of the most stressful experiences of your life. I didn’t find that to be true in my case. It was pretty stress free and Jen and the mortgage broker handled everything. After the inspection of my house. We went back to the seller with what I thought were little problems. I didn’t want to get to nit picky with things but she encouraged us too. The sellers ended up fixing everything on the list. Jen is a go getter. Passionate about her job. You would never be disappointed in her performance.

- Katie G

Jennifer is a great Realtor! She is pleasant to work with, knowledgeable and she will be our representative for future dealings in the area. I would always recommend Jennifer to others seeking representation.

- Paul R

Jen is very knowledgeable and detail oriented. She is also personable!

- Karen R

Jen is a professional and knowledgeable agent who has great experience buying and selling homes! She knows so much a out the process and the homes she shows. At closing time as stressful all the coordination can be, she works her tail off to make sure things go smoothly for her clients!

- Jennifer G

Jen was fantastic to work with and would recommend to anyone!

- Nicholas D

We wouldn't use anyone else but Jen. She's helped us, members of our family and others that we've referred to her to successfully buy and sell real estate in the seacoast area.

- Trustee D

This is our families sixth or seventh deal with Jennifer. She is our realitor!

- Trustee M

Working with Jennifer was a great experience. She had my existing home under contract in a matter of hours and was patient in helping me find and purchase my new home. I would highly recommend Jennifer to my friends and family.

- Karen G

Jen is an amazing asset to your team!


Jennifer is a professional agent who works hard, knows and understands new construction and Condominium sales.

- Leo M

This is the forth or fifth deal we have done together. It was a complex property with lots of challenges. Jennifer did a wonderful job bringing this deal to a closing

- Michael P

I first met Jennifer when she worked with my younger son and his wife over a period of time to eventually find the home they currently occupy. During this period, I worked with Jennifer to purchase and then later sell a condominium. So when a divorce put me in the market for a new home, I again worked with Jennifer to find the home that I am currently moving into.

- Thomas L

Excellent experience. Professionally done with attention to details.

- Paul R

Over a dozen showings, an open house, countless phone calls and texts, sold 1 house and bought another 90 minutes later...who is this Wonder Woman? We have been in our new home for just over a week now and Jen nailed every step along the way. If you're looking for a top notch realtor in the Seacoast, look no further!

- Craig B.

You will have no stronger advocate working for you than Jen. She's relentless in her pursuit of fulfilling your real estate dreams.

- Jason D.

I wish we could give Jen more than 5 stars!! Jen helped us feel confident that we'd not only find a great house but also sell ours, too. She was efficient, knowledgable and supportive starting on day one right through our closings. We are so appreciative to have worked with not only a great realtor, but a kind and awesome person, too. We would HIGHLY recommend Jen to anyone looking to buy (and/or sell) a home. Thanks Jen-we sincerely appreciate all you did for our family!

- The Koelkers

After breaking it off with another realtor I came to Jen anxious and hesitant. I can honestly say she is a Godsend. Our very first meeting she answered every question I had and even took me to see a house! From that day on she never quit. Jen is a tireless and meticulous worker. If she didn't have the answer she'd seek it out. I had limited availability due to my work schedule and somehow Jen made every request I had available. She truly cares and treats every client as family. From calling me at 10pm on a Wednesday to save me from a breakdown, to sending me houses every day when I couldn't bare searching anymore, to just plain checking in on me when she felt I needed it. Calling this realtor incredible does not do her justice, as she is so much more. I would recommend Jen to anyone and everyone. Working with her has been the biggest blessing. She helped make my dream come true of owning my first house and for that I am forever grateful!
