Dr. Lenchner is an excellent doctor who is very thorough, patient, knowledgeable and kind. I highly recommend him as a physician.
Dr Lenchner is an awesome Physician. He listens and has excellent “bedside” manners. He’s knowledgeable and makes sure you understand your medical issues.
My experience with Dr. Lencher was nothing but superb. I've been suffering from vertigo since August 9, 2025. I was referred to him for possible food allergies related to vertigo. Dr. Lechner was very thorough in asking about my medications and questions that could have triggered my vertigo attacks. He went the extra mile to research my medications and ask if I had seen other specialists about my condition. I was so impressed with his sincere attention and care concerning my health issue. It was quite refreshing compared to regular, run-of-the-mill doctor's visits, where you feel like a product going through an assembly line. I wish that he could be a one-stop for all of my healthcare needs.
One of the best doctors of all time
He listens to my outside the box problem and said he needed to do some research on my issue.
I can tell that Dr. Lenchner is genuinely concerned about his patients.
Dr. Lenchner is very thorough and listened to all my concerns. I didn't feel rush and received the care I needed.

Great personality and set me on a healing path for my VERY angry poison ivy rash!
