Very smart, but not available. Staff and office are old and historic. Definetely the world authority. But he has trained many other doctors in Toledo. I prefer going to Toledo Cardiology consults. They are more available, you don't have to wait 8 hours in the waiting room and you can get in right away. You don't have to wait 24 months for your appointment. Dr. Alo has taken over his role nicely.

My father has been seeing Dr. Grubb for over 10 years for orthostatic hypotension. He has been instrumental in making sure that my father has a good quality of life and can be more independent. Always kind, always ready to listen and offer good advice. I would highly recommend him to anyone.

The best Dr for pots syndrome world expert. At the same time humble and thinks out of the box. Meaning he is open minded to other causes that can create the symptoms one is going through. Very cautious. And conservative with which meds for which patients. Always researching.

Dr. Karabin and Dr. Grubb diagnosed my orthostatic hypotension after I tried for 1.5 years elsewhere to get it diagnosed. Dr. Grubb many years later did a cardiac ablation to treat my tachycardia (AVRNT- i think it's called). Then I have been diagnosed with microvascular heart disease (MHD and they have managed me excellently with medication and a cooling vest for the orthostatic and MHD. I would not go anywhere else!

Dr. Grubb is one of the worst cardio docs in Ohio. He misdiagnosed my conditions and just wanted to stick a feeding tube down me. Almost every visit, I left in tears and feeling horrible about the progress of my condition. His NP Beverly Karabin was extremely unintelligible and was not interested in my concerns or questions. I was treated horribly by the staff and not treated seriously. I don't know if this is because I am only 20 years old and a student, but he is one of the worst doctors I have experienced. For being such an "amazing" physician who has spoken about POTS and cardiology all over the area, he was lacking in so many areas. He acted as if he had no interest or empathy towards me and mostly just advertised his writings and articles he had written throughout my appointment. Please don't waste your time waiting 10 months to get into his clinic, you can find better doctors almost anywhere.

Dr. Blair Grubb is worst Cardiologist. He surgically implanted the reveal link in my daughter. The monitor would not send the information to the company or to the hospital. My daughter had this monitor in for 3 months and I called every other day to the office and the staff were so rude and disrespectful. Dr. Grubb is a research doctor and he’s not telling the truth about his credentials. I was charged over $30,000 dollars for the Reveal Link and my husband and I was told the device would be roughly around 5,000 dollars. I have a portion of $3,000 co-insurance that I’m responsible for that went to a collection agency that I knew nothing about until I got a call from them. I’m so upset because he removed the device after being in for only 3months. Dr. Grubb told my daughter he didn’t know why her blood pressure keeps dropping and it was nothing wrong with her heart. My daughter was giving medication that is used for congestion heart failure. I don’t recommend this doctor to anyone. If I could rate a 0 star I would.

TERRIBLE DOCTOR! Waited two hours to see him for new pt app and he spent less than 30 min with me and didn't explain anything, didn't ask if I had questions, didn't order tests, NOTHING. I drove 8 hours to see this guy, what a JOKE.

Dr. Grubb came to see my granddaughter at Toledo Childrens Hospital at the request of her cardiologist. After a long day in surgery he spent over two plus hours with us and he was able to make recommendations and assist in making a perplexing diagnosis. His intelligence, calm demeanor and his willingness to go that extra step for us was truly a blessing. No words to truly express our gratitude!
