Testimonials

I’m a physician myself. This was my 3rd opinion for my horrid eczema. I’ve suffered, sometimes in tears and scratching to blood for years. Dr Koger and her amazing team listened to me, took my history and family history into account, and my desires/concerns for treatment. They provided a plan, samples of medication to try and evidence discussion to back it up.

By visit #2, my eczema was better than in YEARS. A very costly (generally insurance denied) medication was sent to pharmacy, prior authorization completed on the spot, and my medication arrived next day. For a mere copay.

I couldn’t be happier and couldn’t recommend this team more! If you want attention to your issues, commitment to improvement and actual work after you leave the office, K2 Dermatology is for you!

I have a wonderful patient-doctor relationship with Dr. Koger. She remembers our previous conversations which encourages me to be open and honest about any dermatology concerns of mine. I moved out of state recently but still return for an annual checkup. Recently I brought my daughter for a 3rd opinion on her scalp condition because I have so much respect for Dr. Koger’s opinion. This 3rd opinion feels like the right one.

Great, efficient, friendly, and thorough. I get to see them every six months.

My experience at my recent visit was wonderful. The care was highly professional, kind and courteous.
I would highly recommend this practice.
🙏👏

This clinic is compassionate and friendly! Nice assistant, nice doctor and a great outcome with a problem that is painful and embarrassing. Another doctor didn’t even try. Many thanks to K2 in Boulder.

I went into office and all the people in the office were ver professional and greeted me with a nice attitude. Thank you for the courteous and professional treatment had a great experience I will recommend this office to all my family and friends.

I’ve been seeing Dr. Koger for years at this clinic. Very personable with attention to detail and truly cares for her patients. Love all the staff as well. Highly recommend!

After going to several other dermatologists for a seemingly unsolvable problem, this place was recommended to me by one of my physicians. They did a painless and quick biopsy, prescribed me a steroid cream without hydrocortisone in it (finally), and the problem went away in 2 weeks, after two years of struggling. All the while, they were very easy to work with, professional, and kind.

Dr. Koger is an exceptional dermatologist and care provider. Her communication is always clear and concise and she always answers my questions completely thoroughly. I feel truly cared for by Dr. Koger and am grateful to have her as my doctor.

The physicians assistants are always knowledgeable, thoughtful, and very helpful. It seems the entire staff at K2 Dermatology is just wonderful. They are an outstanding asset to this community.

K2 Dermatology (formerly Kallgren Dermatology) was recommended to me by my primary care physician. I have a high opinion of this practice, insomuch as a layman can judge. I never have to wait; they are always very courteous and professional. My practitioner never hesitates to use the liquid nitrogen spray on my small problems, which I think is a good thing.

K2Dermatology is where you want to go! Yesterday the high winds knocked out power to the office; but, all went on as expected. PAC Shannon and Sarah are kind, caring and- interested in you and your skin! 💕

I’ve been a patient at K2 Dermatology for many years now, and I appreciate the thoroughness of my yearly exams. You really want a picky and knowledgeable dermatologist who investigates every tiny freckle and keeps great records about each little mark, and that’s how it is with Physician Assistant, Shannon Ross! Thanks, K2!

My kids and I have been patients of Dr. Koger for about five years. She is exceptionally thorough and knowledgeable when it comes to our various needs, and she goes above and beyond to make sure we are getting great care–proactively checking in to see how a prescribed medication is working a couple weeks/month out. Also, the staff has always been really professional; I appreciate that our appointments run on time.

I came back to K2 dermatology after my previous skin doctor moved away, and they were very welcoming and got me right in for an appointment. They were kind at the front desk and they got me right in to see Shannon Ross, who did a total body skin check and got my prescriptions sent in immediately. Great first visit!

Brenda is really great. Checked out a growth and took a biopsy — pain free. Very considerate about a back spasms that I was experiencing. Very pleasant interaction.

I have had a LOT of dermatology appointments in my long life and this was the best and most thorough of all. Highest recommendation!!!!!

Everyone in this office was friendly, thorough and competent! Highly recommend this practice and especially Kirsten Revitte, PA.

I scheduled a precautionary check up with K2 and was extremely impressed. My dermatologist, Kirsten, took exceptional care to patiently review any potential problem areas and to clearly explain what she was doing and what she was finding. I’m grateful for her help and happy to strongly recommend her.

Great team, great location (for me at least!)
They are always both friendly and professional, always caring and considerate of the concerns and fears we have when considering skin cancer.

The staff always treats you as a personal client

I was greeted warmly by Sarah who got the preliminary information from me and helped to show me where I could get needed services.
Shannon Ross, PA. was a rockstar. She not only attended to my concerns about my health while I was in the office, she called to followup throughout the day to see how I was progressing to get an appointment for an ultrasound. I told her I could get one Wednesday, but she said she wouldn’t be comfortable with that, knowing my family history. So she made an appointment for me near to where I live to get the ultrasound, and gave me a followup call to tell me what the radiologist found, which was no blood clotting. I was stressed out before but her efforts gave me peace. She’s an 11 on a 10 scale. K2 is wonderfully staffed with caring individuals. I hope they all know what an impact they make!

I was definitely a sunbaby in my youth. And since i’ve gotten older, I do Try to be responsible about my checkups… I appreciate your office and the ease of taking care of business, your staff are extremely caring and very patient. Everyone needs to keep in touch with your expertise. To make sure that our bodies get the care they need.

All of the office staff and doctors are very efficient and friendly. My husband and I drive 45 minutes to come to this office. We wouldn’t go anywhere else.

I came in super nervous but my MA and my Dr. were very easy to work with. We had lots of laughs together for my very short visit. They took away any concerns I had and got me taken care of quickly and with care!! Thank you so much!!

Very professional, friendly, and extremely knowledgeable doctors.

When I noticed a troubling skin issue, the office got me in quickly for a check-up. Acacia and Brenda were very professional and came up with a good plan that put me at ease. They were also very friendly and warm.

I saw Dr. Koger for my annual full body check. Appointment was easy to make. It seemed that the doctor did a very thorough job. She was informative as to medical matters. She seemed very knowledgeable to me. She was also very pleasant. I was a patient of Dr. Kallgren for over 20 years and I have found the transition to Dr. Koger to have been seamless. I strongly recommend Dr. Koger and the K2 Dermatology clinic.

Kirsten Revitte was wonderful. In spite of the fact that she has not yet received my records, she had clearly read all the material that I sent in.
She was very thorough in her examination and I felt confident that she would take very good care of me.

Dr Koger is the best!! She found serious melanoma cancer on my shoulder. Had she not found it and removed it I may not be here today. Dr Koger is an outstanding person as well an outstanding doctor.
