Hi, I’m Mary Kate or MK for short.

I’m a classically trained musician, tuner and technician. My love and appreciation for the piano has afforded me wonderful opportunities to learn from talented people.

Having worked alongside my mentor Alex Kostakis at AC Pianocraft since 2020, I have learned the skills to professionally tune and regulate pianos in all conditions. Getting pianos to their fullest potential in both sound and feel is my passion and my goal to is to make your piano sing.

Whether it’s a routine maintenance visit or a major pitch raise, I will bring your instrument back to perfect pitch and make sure every note rings true! From sticky keys, to uneven action I restore smooth responsive play that includes voicing, pedal adjustments and full regulation work to match your playing style.

Reviews

  • Mary Kate was excellent as a piano tuner. She arrived right on time, she worked carefully dismantling parts of the upright, she listened intently, checking the waves of sound with her cell phone. By the end, the piano sounded richer and fuller. I highly recommend her professional skills.

  • MK replied promptly to my inquiry. She kindly answered all my novice questions and asked me the appropriate questions. We agreed on a mutually convenient time, she came punctually, explained the procedure and worked skillfully and diligently. MK spent almost two hours tuning my very old piano and we agreed she'd return in a month to readjust it as necessary. I found her to be knowledgeable, trustworthy and generous with her time. Highly recommend.
