I really like Dr. Klein.

He is a nice guy, down to earth. I have seen six doctors and he is the first one to properly diagnose me with a thyroid problem. My friend told me about him and that he is good with diagnosing unique cases. I was diagnosed with a rare immune disorder. He also discovered a cancer that was causing my calcium to be elevated.

satified with information and will be back for more

He attended to my medications and explained how they would help. He answered my questions and made sure I understood what he was telling me. I felt confident that he cared about my health and putting me on the right track to feel my best. He made me feel as if I could leave the office and follow a logical plan to keep myself healthy. It was a good experience!

Fantastic personalized care from compassionate providers

Dr. Klein and his incredible team have been the most supportive, caring, and invested providers I have ever had. They treat every patient with kindness and prioritize your individual care needs, taking attention to every concern in a timely manner. His patient portal allows quick and easy access to medical records, appointment info, and messaging for questions. Thank you so much, Dr. Klein and the Stages of Life team, for helping me and so many others find good health and wellness.
