About Dolphin

Dolphin Insulation is a family-owned business run by father and daughter, Chris and Amanda Alphen. Chris has been in the home construction and renovation business since the 1980s, and for several years was joined by daughter Tiffany. Amanda joined in 2008 when the company shifted to dedicating itself to insulation services. In 2022, the company officially expanded its service offerings to include general contracting and project management.

Chris and Amanda have educated themselves on how to run a construction business and the fundamentals of building science, and they send their team to school as well, ensuring everyone is continuously up-to-date on the latest technologies and trends. When we assess each customer’s home, we look at how it could be better sealed to retain heat or air conditioning, how home renovation projects can be best executed, and how we can eliminate harmful effects such as allergens and mold to maintain healthy indoor air quality. As part of our aim to be a problem-solving company, we will test products in our own homes and use our knowledge to educate our customers.

I was and still am very impressed and happy about the insulation installed in my attic. I can feel the warm air staying in and seeing the snow on roof not melting away so fast as the attic is well insulated. I would highly recommend Dolphin insulation to everybody.

We used Dolphin Insulation for multiple weatherization items around our house including air sealing, blowing cellulose insulation, etc. From the first contact to schedule the job, to their professionalism, to the quality of their work, Dolphin as a whole is a fantastic group. Highly recommended.

Chris and his team were great. Did fast, efficient work, cleaned up after themselves and were unobtrusive to a family working from home. A great experience!

We thought Dolphin Insulation was great! We had little to no insulation in a home we recently bought. Losing heat and central air running constant was an issue that they corrected for us. We are seeing a huge difference this week with the central AC. Thank you again!!

Amanda Alphen

President

Amanda decided to go into business with her father and sister in 2008 upon graduating high school. Unfortunately for her this was the beginning of a recession. She learned a lot over the last 10 years and feels as though her company is more resilient because of the trials and tribulations that have made them stronger and wiser. The reason she believes they were able to succeed and grow through a recession was because they offered a service that cut energy costs in half, saving people a lot of money. In 2015 she was awarded “Outstanding Woman in Business” by the Family Business Association. She will continue to innovate the industry with unique materials and techniques that create state of the art airtight envelopes for buildings in New England.

Chris Alphen

CEO

Chris has been the successful owner of several businesses but it wasn’t until he started Dolphin Insulation Inc. in 2008 that it became a true family venture sharing ownership with his two daughters; Tiffany and Amanda. Chris’ motto is “take your time and do it right the first time.” His main priority is educating his business and employees so they can stay ahead on new, more advanced techniques that will last for the lifetime of the building. Chris is BPI certified by the Building Performance Institute, Cel-Pak Pro trained through a cellulose provider National Fiber, has completed boot camp for Insulation and Air Sealing at The Center for Ecological Technology, is lead safe certified, as well as Fall Protection, Respiratory, and First Aid trained. When he isn’t at the office, he is volunteering his time to the Rotary Club of Concord and Sleep In Heavenly Peace Middlesex.

Chris Matlick

Building Analyst

Chris came to Dolphin in January 2011 as an insulation installer. He quickly moved his way up to crew lead managing a crew insulating up to 5 houses a week / 20 a month / 240 a year! When you work on this many homes you learn a lot about how they are built differently and where you need to insulate in order to get them airtight, while keeping health and safety a priority. After 5 years of working in the field he became one of our very own energy specialists, performing extensive energy assessments on residential and commercial buildings and creating prioritized plans to bring energy efficiency solutions.Chris is BPI certified by the Building Performance Institute, Cel-Pak Pro trained through a cellulose provider National Fiber, has completed boot camp for Insulation and Air Sealing at The Center for Ecological Technology, is lead safe certified, as well as Fall Protection, Respiratory, and First Aid trained. Recently he attended 475 High Performance Supply’s passive home training to extend his knowledge of vapor smart membranes and high performance insulation assemblies such as Intello and densepack cellulose. Chris has become a valuable asset to our company and our family and is somebody we can all depend on, especially homeowners that work with him. If you get an assessment done by Chris you are in good hands.

Dave Flannery

Production Manager

After joining Dolphin, Dave went to a few jobsites and loved using diagnostic testing to read the draftiness before and after insulating. It made him want to get the number down as low as possible on every project, resulting in the maximum energy savings and airtightness for the building. Being a son to a mother who works at the EPA, he was aware and conscious of the effects on energy use and the environment. He soon became a leader in the field and, over the last five years. has learned everything from insulating to roofing, ventilation, HVAC systems and ductwork, carpentry, drywall, and so much more. Dave is a very hard worker with attention to detail and an eagerness to learn and please. He has trained many of our other highly skilled crew leads and installers and continues to impress homeowners and building owners with the final product he produces. We joke that Dave is among the few in the industry who can manage to make insulation look sexy. He takes pride in his work and the results it brings in terms of comfort and energy savings to homeowners. If you see him on your jobsite, you are about to get a job well done.

Troy Randall

Foreman

Troy has been with Dolphin Insulation since 2016, when he started training under our lead foreman, Dave, and learning about creating high performing homes by achieving a higher level of energy efficiency. He understood how dense-pack cellulose insulation is used in conjunction with different vapor-smart membranes and got to see the results of these products firsthand after completing each job. He quickly worked his way to becoming a crew lead and now manages his own jobs while striving to reduce the homeowner’s energy consumption. He will be the first to go into a crawlspace to stop drafts, even when it doesn’t seem do-able. He is a great problem-solver and has found ways to get a job done when no one else could.

Only 23 years old, Troy is already buying real estate and planning for his future. His constant sarcasm and contagious laughter help everyone get through the dirty, tough jobs and for that we’re very grateful he is a part of our team. He is one of the hardest working people we have ever met and he rarely misses a day of work. He is friendly, fast, and intelligent and will jump through hoops for you, just like a true dolphin!

Karen Silva

Operations Manager

Karen is our hard-working Operations Manager and Amanda’s right-hand WOMAN.

She has been with us since 2015 and, in that time, has dedicated herself to learning all about energy efficiency as she creates plans and proposals for customers’ high efficiency strategies. She manages our office while also doing sales and upholding our mission of providing superior customer service. Customers praise her on how helpful she is and how she makes their experience with us so smooth and painless.

Ryan Preville

Foreman

Ryan joined Dolphin Insulation in 2016 and quickly got his certifications and learned carpentry, ventilation, roofing, building science and how to work with HVAC systems. Everyone that meets Ryan loves him because he cares about the level of service he provides and always aims to please. He is a leader in our company and has a heart of gold. At this point, he has insulated over 1,000 homes and has gained immense knowledge about how homes are built and where energy loss occurs.

Ryan has purchased his own home, become an EMT and volunteer firefighter and volunteers for the Best Buddies program. He will also take your dog out to play during his lunch break!
