Dr. Kirk is passionate & takes his time with his patients. He listens to your concerns & asks questions to root... cause the issue. They use a patient portal with direct access to the team to discuss any concerns that may arise between appts or for medication side effects or refills as well as requesting an appt. Telehealth is also an option which is extremely convenient. I've been seen by a number of practitioners over the years as I have medical issues that require constant care & he is by far the best doc I've had in the last 3 years. I was flying back to Montana to see my doctor there as I couldn't find a local doc who spent the time or listened to my concerns until January when I found him!read more

I needed an appointment and they initiated doing so. I was scheduled in the very near future. My Dr saw that I may... need some leave time from work and provided the paperwork needed in a timely manner as well as in a kind and compassionate way. I also requested my payments since start of treatment and that was provided promptly as well. Tip: Use the patient portal and incessant calls of yours won’t get you a call back sooner. I’m excited for the new office and will get to met Dr in person for for first time. Be ready for tests and and will also offer PCP services. Good luck!read more

Dr. Kirk Tjalas comes highly recommended from me. I feel good, I feel normal, I can focus on an unpleasant task... and finish it, my depression and anxiety are under control, and I no longer feel embarrassed and ashamed that I simply need medication for my mental health.I had to switch providers (always a bit of a stressor), from one who was just adequate, but at least predictable. However, I always felt like I needed to re-justify why I needed such-and-such medications refilled, and was always uncomfortable during my very brief appointments. In fact, the appointments were enough of a stressor I’d often ration my meds just to avoid them. Not very healthy.Dr. Tjalas changed all of that. I found him immediately relatable and trusted him right away. He took control of my situation, reviewed my mental health, and made appropriate changes to my meds. Most importantly, he allowed me to view my conditions as legitimate health problems that required medication to keep under control. Not only do I no longer view my issues as a lack of willpower or somehow fake that I ought to be able to ‘fix’ on my own, I also have the confidence to know I require medication to normalize and contribute. I have the treatments I need, and I will never again feel guilty about requiring them.read more

I've used a few other provider services before, but PMG is by far the best. The level of attentiveness and not... feeling rushed while trying to have a real conversation with your provider is unmatched elsewhere in the industry.read more

I have been with PMG for over 2 years but today had my first appointment with Dr. Kirk and I can already tell that... he is one of the best Psychiatrists that I have worked with. Our conversation felt like a partnership while discussing my treatment options, rather than a doctor just trying to fit me into their own standard regimens. He spent time to educate me on different treatment options and was very upfront and honest. Highly recommend!!read more
