She made a point to try to connect with my kiddo and had compassion for how she was feeling. Really liked her and will go back as needed.

I got referred to Dr. Oberg (specializes in immunology and allergies and such) and he diagnosed me and within a month of his treatment, I felt normal again. For the first time in years!

The staff is also really nice and helpful. I love the lady who takes care of giving shots(forgot her name and title), she's a sweetheart and great at her job.

I appreciate the direct and frank way Dr. Lesser and I can speak to one another. Sometimes in a very humorous, epitaph-filled way. He and his staff really listen to me, don't rush me, and make it as pleasant and hassle-free as possible. He's older like me so he "gets" a guy. But, I took my fiancee to see him and they hit it off too. Seriously, how many couples do that and afterwards feel like it was fun? While he is my doctor, I feel like he's a friend and trusted confidant. He doesn't judge and doesn't force. That's the kind of doctor for me.
