Patient Reviews

Patient

★★★★

The purpose of the meeting was to receive feedback on the testing that had been done. I didn't see much of Dr Klein this time. Rather a Nurse Practitioner named Amanda very capably explained my results in a professional and understandable manner. Dr Klein came in towards the end to see if I had any questions. If some of the explanation details had been on the portal summary, this would be a 5-star review.

Dr. Jason Klein takes an active interest in my cardio issues. I had a heart attack and he is very thorough - orders the appropriate tests and has prescribed medications that have kept my cholesterol and blood pressure in check. I am pleased with Dr. Klein and would recommend him to others. Chris W.

Dr. Klein has performed 4 out-patient surgeries on my varicose veins during the past two years. He is completely professional.He answers my questions pleasantly and completely.I never feel rushed although he is busy. I recommend his services to others without hesitation. Most recently he performed Varithena on a wiggly squiggly mass of superficial veins that pained and prevented me from being more physically active. I am looking forward to hiking more than five miles again in 28 days.I wish I had a picture to post of he and his highly competent team.
