We have been with CRFP for 5 yrs and have had good care from Kristine Beck, but the office staff has been harsh to my daughter, who is 21, for the last couple of yrs. They cancelled her appt with a phone message because they thought she only needed shots, when in reality she really wanted to see her provider! Then they filled the appt without talking to her first! She really needed to see her provider and she's been waiting to talk to her. They pretty much told her too bad. When my daughter turn

Wish we read all these reviews...it's 100% true that this practice just wants $!! They never explain benefits or the fact that different assesments/test given during your visit will end up in $$$$ more billed later!! Front office staff was extremely rude to me and said there's nothing they can do now. Never even called us back for reviewing our results!! Horrible practice!!! Don't waste your time or your $!

Dr. Kasunic's office exists for one reason: to collect your money. If you have extenuating circumstances and want to set up a payment plan, forget about it. They will refuse to care for your children.

I had to find a new Dr when Plum Creek Medical closed down. I had seen this Dr a couple times because of a prescription I take. I needed to get an Rx refill and was told by the pharmacy I needed to get a med check from my doctor, which is fine even though there is no requirement for regular blood screens. $2013.52 later they ran every blood test possible run and for some reason a ultrasound of my carotid arteries. I feel scammed and violated. Never go to this doctor

When I made this appointment, I explained that I needed lab orders for my thyroid that my specialist recommended, and I wasn't sure how that worked. They told me they knew what I was talking about and it was fine. I get here and he says he wouldn't do it and seemed very angry. He said he would either be the one to treat me or nothing at all. I explained I need to see the specialist because primary care physicians back home could not get it straight. He refused, and seemed angry,and just left

First things first. Your people at the front desk are the "face and voice" of your business and they are not friendly at all. Second your MA that takes blood pressure should learn how to treat everyone with respect. This lady absolutely treated my husband poorly because of his size. Dr. Kasunic spent less than 2 min with him and sent him on his way like he was too busy. I see the other Dr. in the practice but will no longer spend any money with them after this experience.

I left this office over 3 months ago because of the horrible communication in that office. I told the Dr. Kasunic about it and he told me to leave the practice even though I had already left but he didn't know. Then I get a call 3+ months later reminding me about an appt with one of the PA's!!???? I laughed and said this is why I left the practice!! No one there communicates with each other or their patients!! This is a bad practice. Stay away!
Aurora, CO |
He as rude, belligerent, called a liar - saying he did not lab results from another doctor, that I know was in my records according to his PA.

I began seeing Dr. Kasunic in 2015 when I moved to Castle Rock based on recommendations from several friends. Practice is a busy one but I never feel rushed--he genuinely seems to care about not only health issues but also on wellness. Does a nice job of educating on what's happening and welcomes active participation in decision making. Definitely a physician I would recommend.
in Castle Rock, CO |
Effective decision maker who is honest, patient and interested in your health. Spends time and money wisely so you can get the services you need at their office. A good go-to doctor for compassionate care.
in Denver, CO |
I had been seeing Dr. Kasunic for years. Then it started getting more and more difficult to schedule with him, so I started seeing other doctors and PAs in the same practice. But then I saw him in an emergency situation (kidney stone), and he knew exactly what to do and did it quickly. There's no substitute for experience.
