A unique quality that Dr. Sam possesses is his ability to treat each patient respectfully and compassionately, regardless of the situation.
Dr. Sam completed his undergraduate degree through University of Michigan in 1993 and graduated from Saba University School of Medicine in 1999. He completed his residency in Internal Medicine in Grand Rapids at Spectrum Health – MSU program. He and his wife Dr. Jain started the practice in 2004. They are both devoted to creating a warm, patient-centered atmosphere that focuses on each patient’s needs. It is important for Dr. Sam to keep up with continuity of care for his patients, especially the ones with complex medical issues. He makes sure to follow up with his patients at all transitions of care (office, hospital, nursing home, urgent care). He makes himself available 24/7 to his patients via pager. When Dr. Sam is not working, he enjoys music, sports and spending time at home with his wife and kids.
Dr. Alka Jain, M.D.
Dr. Jain is a Board Certified Internist who takes pride in having a strong work ethic and meticulous attention to detail. Dedication to patient care is exemplified by her strong interpersonal skills, solid background of medical knowledge, and ability to effectively relate to patient’s needs. These qualities are the backbone for the success of the private practice, Commerce Primary Care, started in 2004 by herself and her husband, Dr. Sam Jonnalagadda. They are as devoted to their family as they are to their patients. She met her husband in Ann Arbor where they completed their undergraduate degrees at the University of Michigan. She went on to obtain her MD from American University of the Caribbean. Her and her husband completed their Internal Medicine Residency in Grand Rapids in the Spectrum Health – MSU program.
Since starting her career in medicine, Dr. Jain has started a very successful private practice and currently serves as the practice manager. She really enjoys the “business” development aspect of medicine. She has also been a medical director for a large Sub-acute Rehab and National Hospice and has worked as a hospitalist. She has served on several hospital and nursing facility committees in relation to Transitional Care, and recently was named to the Board of a Pioneer ACO. As she served as Medical Director for a Sub-acute Rehab, she was blessed to have been able to serve as a physician in so many different aspects of the medical spectrum. With the knowledge she has gathered, she hopes to promote excellence in patient care while developing her passion for transitional care. She is particularly passionate about our seniors, and hopes to help them age with grace.
