Dr. Christensen an his staff are amazing. I have been coming here since I have had my allergy issues food an season allergies an they are great. Dr. Christensen is very nice an explains everything you need to know an answers all my questions when I see him. Thanks to him I feel so much better an can breath again as my allergies are so bad. He is definitely one of the best Allergists in Vegas. Also Imari who gives me my shots is so easy. She never hurts me and is very aware how much I hate needles. She also answers questions that I have an always makes sure I'm good before I go. Lol. The staff is also great an very accommodating when need be. I always try to come on Monday mornings which to me is the least busy, or if I do come in the afternoons I always make sure it's right at 2 o'clock so I'm first to go. I highly recommend Dr. Christensens office and him as a doctor if you have any allergy issues at all. He is definitely one of the best in Vegas
