The best doctor I've ever had and was very effective in treating several medical conditions, recognizing two very urgent conditions and got me to the right specialists right away. Very professional and involved in his patients health. Would and have recommended him to my family and friends.

Dr Loomis is knowledgeable and friendly. His approach to medicine is different than other doctors I've seen in the past. Dr. Loomis practices Lifestyle Medicine and considers diet an important (maybe most important) contributor to both health and disease. He encourages his patients to follow a plant-based diet and tries to reduce the amount of medications taken on a regular basis. He will prescribe medications when they are needed, but prefers to treat most chronic conditions with diet first.

Have been a patient for more than 14 years. A great physician and just a nice guy. He steered my wife and I to a more plant based diet and lifestyle. It helped us to change our thinking and or lives in general. What a positive experience!
