Happy Patients

Look at all these smiling faces!


My appointment with Dr. Sam was extraordinary. This was my first visit with the doctor and never have I experienced a doctor visit like his. Dr. Sam was extremely smart, kind, compassionate and thorough. I felt truly cared about. My faith has been restored in the possible stellar quality care available with my visit. I finally found a cardiologist I feel safe with and whom I trust. He is the best of the best!

Dr. Sam is everything a Dr. should be. He is interested, committed, caring and genuine. He seeks to find the cause of what is ailing you and not just prescribe meds to fix your symptoms. He talks with you not at you, and listens with intent. He doesn’t just tell you what you need to do, he actually works with you, sets up a plan and follows up. He genuinely cares and it shows. Thank you so much Dr. Sam!!! God Bless! You are one of a kind!

I went to see Dr. Sam for a strange heart beat. He quickly diagnosed my issue and put me at ease. He also outlined a plan to get me on the track with diet and medicine to making sure I corrected all potential heart issues I could have in the future. He is extremely compassionate, knowledgeable and trustworthy. I would recommend him to anyone concerned about their heart.

Dr Kojoglanian is by far the best medical professional that’s ever treated me. Dr K called me personally to set up my appointment and actually spent office time to get to know me. My experience with Dr K was indeed unique. The Dr is not one of those who comes in spends 5 minuets..never takes their eyes off the chart or computer screen then walks out. Not only am im confident in his knowledge but his caring is extremely caring. I cant recommend him highly enough.

Dr. Kojoglanian is like the doctors of old. He is competent, kind, compassionate and is a great listener. He is not rushed and will spend all the needed time with his patients. He is an incredible diagnostician and has great bedside manner. When we needed to make an appointment for him to see our son he stayed after hours to make sure that he saw him. I wish all doctors were like Dr. Kojoglanian! I highly recommend him to anyone who needs a top notch interventional cardiologist.

Dr. K is a special man and an incredible doctor. He is full of energy and is willing to take the necessary time to work with his patients. in short, this man will care for your heart!

Doctor Sam is up front and honest with his patients. Compassion and concern are his fortes. He is aggressive and thorough with his diagnoses and has no hesitation recommending another doctor when needed. I would send my friends to him with no qualms.

Dr. Kojoglanian successfully treated me for a 98% closure of the LAD in my heart. Since the procedure. three years ago, he has tracked my progress and continuously monitors my heart. He conscientiously cares about my health. He is a true healer. Thank you!

Dr. Kojoglanian is simply the best doctor I have ever been around. He genuinely cares for his patients and goes out of his way to ensure he is tackling their problems correctly. I have lived in eight different states throughout the U.S. and Dr. Kojoglanian is better than any other doctor I have seen. I recommend him to anyone searching for a cardiologist.

Samuel Kojoglanian M. D. Dr. Kojoglanian is outstanding in all respects. He is warm, cheerful, friendly and is always educating his patients regarding their conditions and what to do about them. I have learned more about my heart condition from him during the last 6 months than I have learned in my 85 years of life. He has inspired me in a very constructive and patient way to lose weight and change some of my lifestyle habits that are contributing to my condition. He has assisted me in battling through my insurance problems when no one else would even try. I am so pleased that he is my cardiologist. I highly recommend Dr. Kojoglanian.

Missy is 80, but acts like she’s 30. Lately however, she slowed down, and complained of chest pains while walking a block or two. Much to everyone’s surprise…


Stretch: stretch your arms, legs and back. You can do it sitting or laying on your back. Raise your hands, lift your feet, and turn your neck (slowly)…
