About

I am continuing to serve as a Practicing Internal Medicine Physician.   The central focus of my care is the individual.   I aim to listen, to understand, to sort out the active concerns of each individual and to address each.  I will actively address any expressed and discovered concern, and will make referrals as needed.   My care aims to be proactive and preventative - to provide screening and advice and counsel regarding health maintenance and wellness achievement.   My care also will address acute illnesses and established chronic ailments and health concerns.   And my care shall embrace and address complex and high risk burdens of illness.   My Calling as Physician is to provide -- and deliver -- personalized care that carefully considers the individual's burden of illnesses, the health changes that she or he is experiencing, and then aiming to carefully provide effective remediation.   I am to actively consider special concerns and fears and needs as they unfold.   It is with humility that I serve in this chapter of my Vocation -- truly taking time to listen, to hear, to respond, to show empathy, and to make deeply considered and personalized clinical decisions. I pledge to serve carefully and tenderly, expressing value, concerns, hopes, counsel and education to individuals as I deliver particulars of clinical care.

I am blessed with good health myself. I have served for over 30 years as Teaching Physician in three University Medical Centers. My teaching harmonized well with my clinical service and patient care during these years. I served both in outpatient clinics and on hospital units, supervising students and residents in concert with direct care responsibilities. These years were fulfilling. I aimed to deliver best care to patients - and I aimed to model best care as well. I regularly talked to students and residents about the special "Calling" of a physician - the privilege, the responsibilities, the duties, and the opportunities to make a difference to individuals and families.  I received several teaching awards over these years, and I received several "Model Physician Awards" as well.  These years were filled with gratification and positive relationships. I thoroughly enjoyed clinical teaching and I poured my heart and mind and soul into each moment.  I served as Associate and then Full Professor of Medicine at Yale Medical School from 1992 to 2014.  During these years, I also served as "Clinical Advisor" to the Chairman of Medicine and I serve as "Advisor" to National Medicare Dialysis Oversight Committee.  I also served as Medical Director of Dialysis at Yale from 1994 to 2014 and as Regional Medical Director of Dialysis for two National Dialysis Corporations from 2001 through 2006.  In these Medical Director of Dialysis Roles, I was responsible for Quality Assurance and Dialysis Safety in local dialysis clinics in New Haven, CT and I also served as a Regional Educator regarding Quality Assurance for hundreds of dialysis clinic leaders across 30 states in Eastern U.S.  In this capacity, I lead the development of several Clinical Pathways which were implemented within the operations of these dialysis clinics and which resulted in high quality care and excellent clinical outcomes.  

In 2014, I retired from Yale University Professorship as Tenured Professor Emeritus - - and I transitioned to serving individuals and families in Skilled Nursing Facilities, providing General Medical care to many persons with various chronic illnesses. In this context, I had the capacity to really take time with individuals --- to sit and listen, to hear and to understand their concerns, and to deliver personalized care like never before.  In this, I realized my Deepest Calling as a Physician -- primary, holistic care of individuals in their own special contexts, delving deeply into their unique social contexts, knowing deeply their burdens of chronic illnesses, responding promptly to any acute health change that they were experiencing, and addressing their various problems and fears.  I took this step in my career journey so that my wife and I could live in a small town in northern Connecticut where our daughter and our grandchildren lived, so that we could help with their care and familly needs.  This step was very positive. 

In 2015, I transitioned to a Community Health Clinic setting, where I served as Primary Care Physician addressing multiple individuals' needs and concerns. It is with humility that I served in this chapter of my "Vocation" -- truly taking time to listen, to hear, to speak, to show empathy, and to make deeply considered, and personalized clinical decisions - and aiming to catalyze positive change in each person's health and sense of well-being. I served as Chief Medical Officer for the CHC into 2017, then transitioned to a Private Practice Group - DOCS of Connecticut.

Through all, I have truly hoped to be a light that shines, just enough to give warmth and illumination and to be a kindling source for others' whose light is dimming or flickering. I have hoped and continue to hope to confer a true sense of genuine caring to each person that I serve - - caring for the person but also caring about the person -- recognizing and serving within their specific social context.

Serving in this way, serving carefully as a caring physician, has been and is my Calling. I intend to serve thusly as long as God wills and by His Strength and Wisdom.

  • Can the hospital do anything for broken ribs?

    Yes. Assess for pleural injury. Assess for lung injury. Tape. Wrap. Secure. Give instructions to prevent pneumonia. READ MORE

  • Taking senna?

    Aiming at root causes is essential. Daily, consume foods that aim colon movements and maintain stool transit and stool texture: these foods include fruits, vegetables, whole foods, whole grains, and at least 2 quarts of fluid per day; best foods are apples, peaches, pears, apricots, broccoli, peas, lima beans, strawberries, blueberries, mango, cantaloupe, melon, olives, and whole grain foods such as high fiber oatmeal, quinoa, unpolished rice. Secondly, minimize simple carbohydrate foods such as pasta, white rice, boxed cereals, white breads, doughnuts, muffins, and dessert foods. Thirdly, avoid substances that adversely affect colon functions: alcohol, tobacco, marijuana, narcotics. And fourthly, senna is a natural fiber that is processed variably. It can enhance stool fiber and stool water. Daily intake can help, yes. And activity is essential: walking, exercising, etc are essential. Rex READ MORE

  • My hernia repair?

    If in the scrotum, it is safe. But it could twist or pinch. So, see a urologist. READ MORE

  • Covid-19?

    Presently, the straightforward way is to proceed to a covid testing clinic site: A PCR swab is necessary; this is a nasal swab sent to a medical laboratory for viral culture and identification. Rex READ MORE

  • Sharp shooting pains after injury?

    Most likely internal contusions to tendon and long nerve branches. READ MORE

  • Pain and severe discomfort with bowel movements and sexual relief frustration?

    Understood. Two major points. First, your colon is not able to provide normal peristalsis. Root cause factors include suboxone, leaky gut syndrome, lectin absorption and resultant colon wall inflammation and colitis. You have “irritable bowel syndrome." This requires expert evaluation and colonoscopy. Remedies include high-fiber diet daily, low saturated fat foods, and prescription medications that restore normal regular peristalsis and moisture regulation of stool. And long-term opiate use of any class and type reduces testosterone to very low levels. It is highly probable that low testosterone levels exist. READ MORE

  • Extreme tobacco withdrawal?

    Adding nicoderm patch will help. READ MORE

  • Very itchy?

    Yes. Your concern is appropriate. Edema is present and not good. Skin breakdown will progress. Bacterial infection will increase and add to skin breakdown. Please inform your care team right away. Elevate lower legs above knees and wrap legs. Antibiotic and diuretic is essential. Causation remedy is essential. READ MORE

  • Alcoholic with bad cough?

    It is very, very good of you to be concerned. A physical examination is important. The likely cause of cough is not directly related to wine or alcohol, but probably a chronic bronchitis is present. Exam with stethoscope and chest X-ray is essential. A spirometer exam in the office of the practitioner is straight forward and will inform about air flow and bronchitis. Simple inhaler intake daily will help. The X-ray will inform regarding possible pneumonitis. Encourage him to be checked please. READ MORE

  • Particles in bloodstream ?

    Blood test particles assessments refer specifically to Lipoproteins that are circulating in your plasma. Lipoproteins carry cholesterol and fatty acids and triglycerides principally. These particles are essential for the plasma carriage of proteins, some vitamins, the various cholesterol compounds, triglycerides and phospholipid compounds. The composition of a lipoprotein particle changes as it circulates throughout the bloodstream because these particles will release some carried compounds and will pick up other compounds. The function is "carriage protein." So, particle count is a concentration per milliliter of plasma. The higher the particle count, the more concerned one would become, as the count reflects cholesterol and triglyceride principally. The particle count thus is an indicator of cardiovascular disease risk READ MORE

  • Lump in upper-right chest area, severe pain in armpit and shoulder?

    Please present for a physical exam and blood work and diagnostic imaging. The cause and nature of this requires exam and focused imaging and blood testing. Rex READ MORE

  • Possible aspiration of vomit?

    Hello, I advise going to either a hospital ER or Urgent Care to have an examination and chest X-ray. Rex READ MORE

  • Yellow nipples?

    Skin should be pink, dark pink. Yellow color means reduced blood flow. Yes. Be checked. READ MORE

  • Covid19 antibodies?

    Hello, Specific virus antibodies that develop from invasive infection help your body resistant subsequent same-virus invasive infection. If the same genus-species virus is inhaled by you, that virus will be attacked quickly by your specific antivirus antibodies. Your immune response will engage within hours of colonization in your nose or throat and will eradicate the specific virus over several hours. Nevertheless, your skin or clothing or hair can hold a virus for a short time. The natural antibody development and any vaccine-induced antibody development protects you from invasion and illness. Your nostrils can be swabbed for influenza A and for influenza B and for coronavirus to determine if your nasal passages carry any such virus. Vaccination intends to protect you and to minimize virus reproduction within you. Hence your contagiousness is much much much less, as is your vulnerability. Cleaning nostrils is essential for all people. This rids nasal passages of any virus. Gargle accomplishes the same in throats. Hand washing accomplishes disinfection as well. The true news is that Betadine Nasal Spray is germicidal and protective and the most effective action that anyone can do to protect self and others. Betadine Nasal Spray is MUCH more effective than any mask. Betadine Nasal Spray is safe, studied, effective, and available worldwide. Essential personal hygiene is the optimal WAY. Betadine Nasal Spray is cornerstone to nasal nostril virus-eradication and hygiene. (I am politically non-aligned) Rex READ MORE

  • Accidentally swallowed a fish bone?

    It is possible for a a small bone to get stuck at the laryngeal region. Small folds and pockets exist there. Symptoms could include what you describe. Be examined. READ MORE

  • Vitamins?

    Biotin is vitamin B7. Biotin is contained in many foods. Between 50 and 100 micrograms per day of biotin is recommended for adolescents and adults. Biotin is water-soluble, so extra intake of biotin will simply pass through your body when you urinate. And most people can handle biotin supplements with no problem. However, some people report mild side effects including nausea and upset stomach and irritable bowel. There are no known toxicity symptoms associated with too much biotin. The dose you ask about is excessive, though unlikely to be toxic. Wiser to supplement with less than 10,000. Recommend 1,000 mcg instead. READ MORE

  • Question regarding having adverse side effects after mrna vaccine?

    Agree that second mnra shot may trigger another adverse reaction. Meanwhile, high intake vitamins and minerals and poly phenols and anti oxidant diet is essential. Exuberant exercise plus deep tissue massage are essential ongoing. Stretching and yoga stretching are essential. Obtain Gundry Vital Reds and take two scoops per day. Same with Power Blues. Really boost your immune wellness and recovery. Ongoing 4-6 months at least. Biotin 10000 mcg per day. B12 100 mcg daily. Thiamine daily. Magnesium 400 mg daily. Green tea extract 400 mcg EGCG DAILY. Vitamin K2 90-100 mcg daily. For virus protection, use Betadine Nasal Spray one spray every other day. Superior to masks. Superior viral eradication of all kinds. READ MORE

  • Taking Aleve and Tums together?

    Hi, Yes. This combination is safe and prudent. Aleve is capable of thinning stomach protective lining and allowing gastric acid to be irritable to stomach wall. Tums acts to reduce gastric acidity because it buffers acids. So, it is wise. And helpful. READ MORE

  • Vaccine?

    There is a clear trend toward the worldwide prevalence of *MTHFR* 677 and COVID‐19 incidence and mortality. Published data exist documenting this observation that disease from COVID may be more severe. HOWEVER, the vaccine is not considered unsafe or contraindicated with MTHFR. The vaccine is considered helpful to prevent COVID in you. Long ago, the polio vaccine was questioned as unsafe, but the actual data with review did not contraindicate any vaccine in the setting of MTHFR -- most importantly, be sure your intake of B vitamins is sufficient and daily and that your intake of FOLIC acid is daily.

  • Pea sized thing moving freely on the right side of my scrotum and it isn't the testicle?

    This may be a small, firm cyst; cysts of the epididymis can form; and cysts of spermatic cord can form. Be examined by urologist and by ultrasound. Rex READ MORE
