These quotes represent just a few of the many positive reviews that we have received for Dennis Siefker. We don't pay anyone to provide their review and they are all made voluntarily. Some people's experience receiving therapy with Regain might be different.

Dennis has been beyond belief the most helpful and respectful person myself and my family has worked with. He has been understanding and supportive through all aspects of our therapy.

Dennis is an amazing couples therapist and I would recommend him to anyone looking to improve a relationship. He is skilled at active listening without judgement and sheds light on things in a way you probably have not yet considered. His feedback is illuminating not just about the relationship, but about the individual self. He provides many helpful resources to supplement the weekly sessions which is beneficial because couples work is continuous, rather than just something you participate in during therapy. My fiance and I were in a very bad place when we first sought professional help. Now with the tools and skills that Dennis has helped us to sharpen, we are confident, happy, and ready to enter marriage with a newfound loving perspective that will be our foundation for decades to come. Thank you Dennis!
