I can confidently say that my first appointment with Dr. Lessow was the best physician's visit I've ever had in my 31 years. I had originally booked on Zocdoc, but my appointment was canceled without any reason, but I called the office and they were quick to set me up with another appointment right away.

Due to my allergies I have a lot of sinus and ear issues. Doctor Lessow has been the best doctor. My issues are minor compared to all of the serious patient illness she treats. Regardless of your condition she takes the time with you. She keeps detailed records using her lap top.

Dr Lessow is wonderful. She is kind, patient and thorough. Her staff is very sweet and helpful. Plus, her office feels like you're in someone's living room and not in an office.

I have been dealing with dizzyness for two months. I had one doctor misdiagnose me a vitamin deficiency. My primary doctor blamed elevated blood pressure (140/85) and put me on meds. Still, the dizzyness lingered. After reading about others with similar symptoms, I decided to visit Dr Lessow. Dr Lessow quickly set me up for an ear and head MRI to rule out any serious conditions.

- Cesar A.

Dr. Lessow and her staff are fantastic! From my first phone call to inquire about setting up a consultation, the entire office has been extremely helpful, warm, cheerful and professional. Dr. Lessow always listens attentively to all I have to say about my symptoms, asks great questions, and gives me several options. I have never felt pressured or rushed, and am always confident that she has my best interests in mind for long-term health and comfort/healing.
