Dr. Thiesen and his staff are absolutely amazing!! Dr. Thiesen is extremely knowledgeable, caring and his staff is very helpful, responsive, courteous and professional. As a patient of Dr. Thiesen, I have elected to take a peptide , CJC and have lost lbs and built up my muscle. My work outs are amazing now! I feel amazing, my skin texture and elasticity has improved so much that I'm in disbelief when I look in the mirror. Dr. Thiesen has also put me on BHRT and that has also improved my laundry list of mesopause symptoms I was having. I highly recommend Dr. Thiesen for all you need because he comes up with creative treatment plans and he's willing to try new approaches that are safe and proactive. We just love love love him and his team!
