5 /5 S Pat: Today I just had to give my high opinion of Sierra. Ive been seeing Sierra for about three years now after I had a lumpectomy and radiation for breast cancer. I cant say enough about how happy I am being under her care. First of all, I have never had so much confidence in a medical professional in my life. Sierra gives me my anastrozole/testosterone pellet every 4 1/2 months or so. She also gives a thorough evaluation of my bloodwork, etc. She is on top of every detail and never forgets anything. Its amazing how dedicated and caring she is toward the individual. I feel like shes a daughter caring about her own mother. We had a conversation 5 months ago and she remembered all of the details. I am so blessed to be able to see nurse practitioner Sierra and I highly recommend Colbert Institute of Anti-Aging. Oh, I am still cancer free, had amazing results on my bloodwork, and feel fantastic with the pellet and supplements that Sierra recommends.
