Tammy is AMAZING! She will make you feel right at home for those who may have not have always had a specific hairstylist to go to or who may be a bit nervous to go to someone new. At this point I just show her a picture or describe what I want and she makes it 1000x better than what I’ve imagined!

I came in an absolute wreck.. roots over grown, box bleached hair turned yellow, and not feeling my self whatsoever. When I walked into my appointment with Tammy, I didn’t even have inspo pics.. I was absolutely stumped on what to do with my hair. All I said was “help” and let me tell you, she did the damn thing. my hair has never looked so good. I walked into the salon unsure and insecure.. I walked out feeling confident and bad ass! Tammy Kiefer absolutely rocks. She knows exactly what to do and how to do it! I absolutely will be coming back. Thank you Tammy!

Tammy is the best! I’ve been going to Tammy for several years and she always does an amazing job with both my cuts and color. She really listens to what I want, pays attention to the details, and I always leave loving my hair. She’s also incredibly personable and easy to talk to, which makes every appointment a great experience. It’s hard to find someone who is both genuinely talented and someone you enjoy spending time with, and she is definitely both. I’m so glad I found her and wouldn’t trust anyone else with my hair!
