Personalized Care from a Doctor who Cares
Healthcare should be more than prescription drugs and quick fixes. Our philosophy is simple: When your body is properly supported, it has a remarkable ability to heal itself.
It’s time to optimize that potential.

Care Beyond Conventional
Dr. Rajender Singh’s unique approach involves a powerful combination of traditional primary care, functional testing, and integrative medicine practices, giving your body the specific support it needs to thrive. We prioritize understanding the root causes of your health concerns, rather than masking symptoms with medication.
So, if you’re tired of the “pill for every ill” approach to healthcare, rushed visits with a doctor who doesn’t know you, and cookie-cutter solutions, then it’s time to experience exceptional primary care that empowers you to restore your health and wellness.
Because when it comes to your well-being, we believe you deserve a physician who treats you as a whole person, not just a collection of symptoms.

EXCELLENT Based on 20 reviews Charles Cody2024-08-20Trustindex verifies that the original source of the review is Google. I have been under the care of Dr Singh for 20+ years and now drive over 200 miles for each appointment just to keep him as my major health care provider. Dr Singh is an exceptional Medical Doctor which is most difficult to find these days and I know this as I have lived all across the United States. Also, if you need to see a specialist, which I have had to do many times, Dr Singh has great medical specialist connections and can get you in to see them fast! I have NEVER been disappointed, just highly impressed! If you are seriously looking for the best medical doctor and the most excellent health advice, then I highly recommend you establish a medical patient relationship with Alpha Medical's Wellness Group in Alpharetta, GA. In addition, Dr Singh's staff is tops, --- making Appointments to your convenience , customer service/ questions, getting prescriptions to pharmacies/ refills and putting you directly in touch with Dr Singh if necessary. They are simply OUTSTANDING! I expect to be under the care of Alpha Wellness/ Dr Singh the remainder of my life....... Charles Cody Young Harris,GA Jim Minter2024-07-09Trustindex verifies that the original source of the review is Google. After dealing with several intractable health issues, I begin diving into medical health on my own. There is so much new information coming out right now that most doctors in the field do not have time to catch up. A friend of mine recommend I come and talk to Dr. Singh. We had an amazing conversation. He is an excellent blend of traditional western medicine and all of the new functional medicine that is coming on the scene. (Huberman et al.) I have shifted the entire way I approach my health and well-being. And he has been the guiding hand. I recommend him without reservation. Michele Maddox2024-07-03Trustindex verifies that the original source of the review is Google. I am so grateful to have found Alpha Wellness at a low point when I was developing deep concerns for my overall health. I needed a doctor who would take the time to listen to me and address my greatest challenges. My prescriptions had reached 11 pills per day and my health seemed to be deteriorating. Dr. Singh's holistic approach took into consideration my mental and emotional state as well as my diet. I am 76 and this was the very first time the analysis of my symptoms had been approached in this way by any doctor. With the right testing we immediately discovered some of the answers I needed. I am getting better and better. I feel safe and protected, and I have already strongly recommended Alpha Wellness to family and friends. Alpha is a team of healers. This is what medicine should be all about. . Alejandro Arrese2024-07-02Trustindex verifies that the original source of the review is Google. This is what medicine is supposed to be like. Proactive and based on root causes vs reactive and treating symptoms. I’ve never been healthier. Highly recommend Perlinda Hudson2024-06-30Trustindex verifies that the original source of the review is Google. I have been under the exceptional care of my internist physician Dr. Singh for the past 18 years, and I couldn't be more delighted with the addition of holistic medicine to his practice. His expertise, knowledge, and patience have always been exemplary, and now with the holistic approach, he offers a well-rounded and comprehensive care plan for me and my husband. Not only is Dr. Singh outstanding, but his receptionist Ella and his nurse Serena are also extraordinary. They are efficient, caring, and ensure that every visit is smooth and comfortable. Their dedication to patient care is truly commendable. I am grateful for the ongoing care and support provided by Dr. Singh and his team. Their professionalism, dedication, and compassion make every visit a positive and reassuring experience. I wholeheartedly recommend this practice to anyone seeking high-quality medical care with a personalized touch. Jan Hansen2024-06-28Trustindex verifies that the original source of the review is Google. Alpha Wellness (Dr. Singh) is an exceptional medical provider. I have been a patient of Dr. Singh's for over 10 years and I have never been disappointed. Most recently, he transitioned to concierge medicine and it has been a game-changer for me. I truly appreciate the time Dr. Singh dedicates to each appointment, focusing on "me", "listening" to my concerns and working toward the root cause of my issues rather than treating just the symptoms. I appreciate his holistic approach and his attention to gut health and the impact it has on our physical and mental wellbeing. I am happy and excited to continue my journey of wellness with Dr. Singh and the Alpha Wellness staff....who are also awesome, friendly, attentive and supportive. Mary C. Scarboro2023-02-01Trustindex verifies that the original source of the review is Google. I assisted Dr. Singh years ago in his medical practice. I would rate Dr. Rajender as one of the very top practitioners I have the pleasure to work with. His deeply caring and involved with patients and I was impressed by his intelligence and clever management. I have recommended him to all friends and family members.
