Dr. Brent Sigler, MD

Dr Sigler informed my 26yr old daughter that her biopsy was positive for Merkel Cell Carcinoma. After researching this aggressive form of skin cancer, we found that it is extremely rare in patients under the age of 50. Naturally, we sought out a 2nd opinion and scheduled an appointment with a UC Oncologist. The Oncologist requested the pathology report from Sigler’s office and later that same day my daughter miraculously received a call from Sigler’s office apologizing for giving her an incorrect diagnosis. Turns out, they put another patient’s pathology report in my daughters file. I understand that mistakes can happen but the 2 weeks of unnecessary stress his office put on my daughter and our family is inexcusable. I sympathize with the patient that actually has Merkel Cell cancer but I can only hope they read this review and will seek a more competent provider.

staff was very inexperienced, after I made a appointment and went to it. I found out they would not accept my insurance. The appointment was only ten minutes and double checked to see if they accepted my appointment. Staff was stuck up. Told me to go to Denver Health. There are several hospitals like CU Health, Rose, Porter, etc. Staff was a royal witch.

If you want a Dermatologist that is experienced, knows his profession, highly recommend Dr. Sigler. Had a severe condition that two other Dermatologist could not diagnosis or know how to treat the condition. Other doctors had taken biopsies, skin grafts and Dr. Sigler solved my condition in six weeks without guessing games. If you want results, this is the doctor you can trust.

He is very caring and puts you at ease. His surgical skills are outstanding. My whole family, neighbors, and co-workers swear by him.

I seen Dr sigler today, he is truly an amazing doctor I was very nervous to have a biopsy done he is very reassuring and gentle I didnt feel a thing. His staff great!!!

The office of Brent Sigler and staff are always willing to help. The office is very knowledgeable and professional. You find another team of compassionate people. They genuinely care about their patients. I have personally experienced them go above and beyond, not only for me, but other patients in the waiting area. Sometime there's is a bit of a wait to get in, but they are worth the wait. If you unsure of which Dermatologist to choose, you can't go wrong with Brent Sigler's Dermatology Team.

Dr Sigler and Staff are amazing. Don't even think about going to anyone else.....

I have been seeing Dr Sigler for over 15 years, incredibly friendly, efficient and trustworthy.

Nice man, nice office :)

Friendly and my skin is looking better :)

Dr. Sigler is fantastic. After looking for the right dermatologist for years, my frustration is finally gone with Dr. Sigler. He has greatly improved my skin, as I genetically have dry, bumpy, red, skin. When I ask questions, he answers them with honesty and with facts, not covering up anything at all. He has great products, which have, I believe, prevented many acne breakouts. Highly recommend Dr. Sigler!

Expert care and prompt service.

Brent Sigler is the worst doctor in Colorado. He is not a caregiver, he is merely a clinician. His staff is lazy (they won't even look for the paperwork you completed - they will try and make you fill it out again), rude and unprofessional,. Dr. Sigler is an arrogant jerk who does not care about anyone but himself. He rolls his eyes and gets annoyed if you ask questions. He is openly rude and disrespectful to his wife, who works in his office. I think Dr. Sigler does more harm than good f

I have been a patient of Dr. Sigler's for over 20 years and have always been pleased and confident in his diagnosis. His office staff has always been courteous and helpful.
