Sandy Harshaw-Irvin, BC-HIS

Board Certified Hearing Instrument Specialist

Hi! I’m Sandy! I have dedicated 30 years to providing hearing health care to our patients at Hearing Aid Institute. I was honored to become our Regional Manager for the State of Montana in 2012. I work mostly out of our Great Falls office and the Hi-line. I have had the privilege of going with the Starkey Foundation on one of its missions to Mexico. It is a life changing event and wish everyone could experience it for themselves. I have raised two beautiful daughters; the oldest is now working with us which makes 3 generations; the youngest is in college. I have a wonderful husband and 2 step daughters. I am involved in Awana and piano playing for church and have been a 4-H leader in my community for over 15 years. I look forward to helping you “Hear the Beauty of Life”!

Daniel Leishman, NBC-HIS

Nationally Board Certified Hearing Instrument Specialist

I love spending time with my wife and three children. I have two boys and a girl, and I married the most amazing woman in the world. My wife and I have been married since 2010, and we’ve enjoyed every minute. I have a special interest in the hearing health industry. My grandfather lived with us for many years when I was younger. He had a severe hearing loss and no one ever helped him to hear better; it broke my heart to watch him miss everything in our lives. Consequently, I have an insatiable desire to give life back to those with hearing loss.

I am a Nationally Board Certified Hearing Instrument Specialist as well as a graduate from Brigham Young University. I operate solely with the needs and concerns of each patient, and I maintain the highest professional standard of care. My experience and love for life provides me with a transcendent capacity for hearing health care.

Audio Technician

Hi I’m Melissa, but you can call me Missy. I am a native Montanan, proudly born and raised in Great Falls. I’ve worked with the geriatric community in some capacity since 1987. In 2007 I was offered the amazing opportunity to work for Hearing Aid Institute. Knowing from my experience how hearing aids improve people’s lives, I jumped at the chance to work in this industry. I did leave for a couple of years but now I’m back, and I am tremendously excited, eager and committed to saving hearing lives. I love the fact that we are restoring quality of life to our clients through our NuEar instruments, products and most importantly our service. In my off time, I am very fortunate to share my life with my best friend and awesome hubby Richie and our blended family of 4 wonderful kids and 9 phenomenal grandchildren that keep us very busy! And we love every minute of it!

Both of us (husband and wife) wear hearing aids, and have had excellent service from the entire staff. If I need something quickly and drop in, Autumn, the receptionist, tries her best to get me what I need and usually succeeds. Great service, knowledgeable and friendly.
