Patient Reviews
Apr 30, 2026
DR Lesieur is a very compassionate Dr. The first time I met DR Lesieur I noticed right off that as we spoke she was listening closely and not prejudging what we were discussing as some Drs sadly do. She very professional yet like Dr Santana speaks to you so you understand everything before you leave her office. When she's prescribed medicine she is quite thorough as to why she's recommending, how you should take it, and the length of time and always mentions any questions don't hesitate to call. I've only seen Dr. Lesieur in her office so I have no idea regarding teleheath visits. I would recommend her whether you're young or older. Dr. Lesieur is a DR. ,who when you leave her office, you leave feeling like your her most important patient. A rare quality these days.
