For much of my life, I have had a fear of dentistry that has prevented me from scheduling routine visits and from maintaining dental health with a professional. After having done research to find a dental office who understood my anxiety, I scheduled procedures to be completed under general anesthesia by Dr. Van Hilsen of Rocky Mountain Anesthesia Group. I cannot give a greater recommendation for anyone (child or adult) requiring anesthesia for surgical or dental procedures. Dr. Van Hilsen handled my nervousness with the utmost compassion and professionalism, even making me laugh before I went under. I woke and 'came to' after two hours of dentistry, having felt no pain, feeling fully comfortable under the administration of his anesthesia. I cannot give enough sincere praise of Rocky Mountain Anesthesia (and of Dr. Hoang of Simple Smiles in Lakewood), because for the first time in years, my oral/dental health is back to square one and I have completely overcome my phobias. Thank you, Dr. Van Hilsen!
