“It’s been an absolute pleasure working with Johnny Mollampour and the MJM Interiors team over the past 10 years.  After the initial meeting, we were extremely confident that Johnny and his team would be the perfect choice for our extensive home renovation and decorating project. 

The team brought much more to the project than could have ever anticipated.  His attention to detail and budget, combined with his design sense and wealth of knowledge, were invaluable. Johnny worked closely with us to embellish the architectural drawings.  He provided us with detailed CAD design drawings and walked us through each step of the design process in the build. He selected all the materials and custom-designed all the cabinetry. The furniture and lighting were tailored to perfectly match the house both indoors and outdoors.

If you have the honor to be selected as a client, we know you will be more than satisfied with this amazing professional team.”

“Our project was unique.  The goal was to build a sustainable, green, practical and organic home that was still stylish.  Many qualities and features weren’t standard.  Johnny is gifted in thinking outside the box.  He was able to meet the challenges.  He was extremely talented in holding a wholistic image of the project and incorporating our personal desired features to enhance the end result and avoid clashing elements.   Above all, his best quality is his commitment to his clients.  At times, we fell for particular elements that weren’t a good match for our house, but we were too attached to them.  Johnny had a humble way in skillful communications to ground us back to the reality.  Most amazingly, I believe he dreams in colors.   All the colors he picked for the stones and finishes resonate in harmony so magically and naturally as the rainbow!”

“My husband and I met Johnny nearly twenty years ago. We were recently married and wanted to make some improvements on our 1920s Spanish-style home. Johnny helped us make the house so beautiful! I was a novice to the world of home decorating, and Johnny was such a great guide. He showed me all the possibilities and helped my husband and I make choices that reflected our personalities and our needs as a new family.

Johnny’s work ethic is incredible, and his customer service is second to none. He is responsive, patient, flexible and conscientious. We look forward to continue to work with him and his team, wherever life’s adventures might take us.”

“Johnny is the best designer & his personality is absolutely stellar!  His talents include everything from event planning & coordinating to interior decorating to full-on construction.  I thank my lucky stars to have found him!  He’s professional, tasteful, thorough, reliable, thoughtful, personable & very reasonable.  He always goes the extra mile without you having to even ask.  Basically, he’s not trying to make his annual income off of you like many of his competitors.  I’ve worked with Johnny on multiple projects & I refer him to everyone.

If I could describe him in 1 word it would have to be ‘FABULOUS!’  He has my business & my trust.  I would never consider working with anyone else”
