Just a note to say how thankful I am you found my blood clot/blockage in my leg. After several MRI’s, CT scans, ultrasounds at the hospital, and several visits to surgeons and doctors offices, I was told that there was a 30-40% blockage. My leg continued to be in pain. I was referred to Joseph Matthews in Dr. Shaheen’s office where he discovered, though his ultra sound testing/procedure, that I had 100% blockage in my left leg. Because of the ultra sound by Joseph Matthews, Dr. Shaheen was able to schedule me for a procedure to remove the blockage. Since the procedure, I walk with no pain in my leg. Thank you.

I had the pleasure of working with Joseph Mathews in my office from January, 2014 until the
end of June, 2017. Joseph is a certified ultra-sonographer who carried out M-Mode and 2-D
cchocardiogram-Doppler studies, renal-duplex scans, Carotid-duplex scans, and peripheral
arterial and venous studies in my office. He also carried out Ankle-Brachial Index studies.
He provided his own cchocardiographic and peripheral vascular Doppler equipment, while I
carried out the interpretations of the studies.

I was impressed by Joseph’s reliability and willingness to make extra effort to provide these
services for my patients. On rare occasions, he went so far as to go the home or skilled nursing
facility to carry out the study, when the patient was immobile and unable to come to the office
for the study.

I was also extremely pleased by the quality of his work—paying attention to details, by checking
for presence and grade of LV diastolic dysfunction, and by labeling structures he was viewing to
make it easier for me to confirm his findings. He filled out a preliminary report that I would
modify or accept fully, if no changes were needed.

We worked in a collaborative manner, and Joseph was open to my suggestions for improving the
studies, if I needed additional data.

I would strongly recommend Joseph as being an outstanding ultra-sonographer for future work in
a doctor’s office.

I have closed my clinical cardiology office on June 30,2017 after 46 years in the same Medical
Center, and I will miss the collegial interactions with Joseph.

If any additional information is needed, please do not hesitate to contact me.

Yours truly,

Message: Good morning, Joseph, It was fun and quite informative to become acquainted with you at the Vascular Clinic yesterday. Your level of cordiality, competence, communication and, especially, attention to detail were exceptional. After you pointed out your observation of some edema in my left foot I was able to more accurately track it back to a gym injury and not vascular related. Thank you. Your web site is a revelation. I will be a regular visitor for your updates and, although retired, I will introduce a number of colleagues and patients to your services. Your pricing seems economical and the services are appropriate for many patients, especially those home bound. Best, David David D. Hunt, M.D.

If you need an Ultrasound done, look no further. Joe took the time to show me the images, explain thoroughly what I was looking at, and for the first time since I fell sick in Dec 2012 do I understand what is going on.  I feel very confident putting my health concerns in the hands of this team.

Thanks, Joseph!  I really appreciated your thoroughness, professionalism and kind nature… I will definitely recommend your service to others!

My name is “CR”. I know this is random, but I wanted to say thank you from my mother and I. I am currently a nursing student at (a local college). I was talking to my mom about it and she said, “Do you remember that ultrasound tech that helped save me?” I just wanted to thank you, from her and I, for helping to save my mother’s life. You did an ultrasound on her to measure her abdominal aortic aneurysm, in addition to this, you detected that she had severe kidney stenosis. She is stable now, thanks to you. You went above and beyond with your job and helped my mother at a time that I was struggling more financially. You offered her your services for free, without the blink of an eye. I remember when you would go to events where you did carotid ultrasounds for the public for free! After you traveled to Switzerland you were so nice, you brought back a bag of tea. Thank you for your kindness. You are truly a caring person that has and will continue to make a difference in this world. I am grateful to and for you. Wishing you a happy new year and many more blessings your way.

Thanks. I appreciate your attention to customer service…pretty rare in the healthcare industry! Keep up the good work.

I’m scheduled to have my left leg done next Wed. I’m very excited!
I want to thank you so much for taking such good care of me and discovering what you did. You were wonderful !!! Always smiling!

Dear Joseph,

I am so glad I found you on the web. I left you a review on the Yelp site.
I am sure we will meet again and I will be singing your praises to everyone I know.

Regards,
NC
