Ketel Thorstenson, LLP (KTLLP) has recently joined the ALS Association’s Community of Hope by creating a personal tribute fund to honor Merle Karen, a recently retired partner at KTLLP, who was recently diagnosed with ALS. To kick-off the fundraising KTLLP has pledged $5,000.

ALS, commonly called Lou Gehrig’s disease, is a devastating neurodegenerative disease. There is currently no known cause or cure. To learn more visit the ALS Association website at

Merle, and wife Gena, have been Rapid City residents for 45 years. The list of their community involvement and contributions is long, and was done out of love with no expectation of recognition or fanfare. Merle’s work history is much the same. Going the extra mile to help clients has always been a standard for Merle.

Given Merle’s contribution to KTLLP and the Black Hills community, his co-workers, and friends wanted a meaningful and impactful way to show support. During tax season (January through April) KTLLP will hold a Penny Drive. All KTLLP offices (see list with addresses below) will have collection containers for donations.

Another option for giving is by visiting the KTLLP Community of Hope tribute fund webpage, named Merle’s Mustache Mob. Secure, online donations can be made there. Gifts to this worthy cause are tax-deductible.

Contributions will:

  • Fund global, cutting-edge ALS research initiatives directed at the cure.
  • Support compassionate, high-quality care and resources for people and families affected by ALS.
  • Raise awareness for this horrific disease through national public policy initiatives.
