Shelly Dretzka, Owner, AHRrow

After 25 years on the “inside” of HR—navigating everything from high-stakes employee relations to building performance cultures—I took the leap during the pandemic to launch aHRrow, a people-first HR consulting firm for small businesses with less than 100 employees. Bringing multiple decades of HR experience, positivity, and energy, I partner with leaders who are ready to grow, delegate, or simply step away from daily HR headaches. At aHRrow, we specialize in streamlining all things HR, from resolving employee conflicts and shaping talent strategies to building practical, results-driven performance frameworks. Our collaborative and proactive approach ensures your company’s culture, priorities, compliance and budget stay at the forefront—so your HR works for you, not the other way around. In the free time I’ve created for myself through entrepreneurial spirit and an empty nest, I enjoy spending time with my husband, two adult sons, daughter-in-law, and friends— usually outdoors at our cabin in Black River Falls, fishing, kayaking, UTVing, or out on the golf course working on my consistently inconsistent game.
